Scattering by particles of complex shape such as concave particles, torus, or clusters of fibres can not normally be computed using the T-matrix method. In this paper we are proposing a decompositioning approach to handle this scattering problem. A scattering particle is decomposed into a number of basic units and scattering by such an ensemble of basic constituents is computed using a multiple scattering T-matrix approach. The range of validity of this approach is investigated by providing exemplary computation results for single fibres and aggregated fibres.://000255648500008sISI Document Delivery No.: 297WQ Times Cited: 1 Cited Reference Count: 18 Wriedt, Thomas Schuh, Roman Doicu, Adrian 0934-0866Part.

The investigation is focused on an optical measurement setup with an elliptical mirror as the main optical element. In order to evaluate the capabilities of the individual inversion methods, light scattering by spherical particles is simulated in the size ranges of 0.1 - 10 mu m and 0.05 - 1 mu m. The distribution of the particle diameters is modeled with three different parametric functions, i.e., RRSB, logarithmic-normal and a more specific distribution from an ultrasonic nebulizer. Different kinds of noise, e.a., additive and/or multiplicative, are applied in different levels to the simulated scattering measurement to include real physical measurement conditions. The convergence properties of the scattering simulation are investigated with respect to the number of size classes, and thus, information concerning the size resolution required to simulate a measurement for a given particle size distribution is obtained. Further parameters of interest are the minimum angular resolution of the measurements, the number of size classes of the retrieved particle size distribution and the measured polarization of the scattered light.://000259546100002iISI Document Delivery No.: 353DK Times Cited: 0 Cited Reference Count: 50 Riefler, Norbert Wriedt, Thomas 0934-0866Part.

Commercially available inkjet printing devices are not suitable for producing such droplets since they produce satellite droplets. Furthermore, standard drop-on-demand devices are normally restricted to the generation of droplets with the same size as the orifice diameter. Using a new and more sophisticated computer-based signal generation system, smaller-sized droplets can be generated from the same orifice. A key feature of the design is the generation of freely definable pulses. This enables the generation of acoustic modes within the fluid of the droplet generator, which leads to the generation of droplets without satellites. Only very few pulse forms enable the generation of suitable acoustic modes. Therefore, it is necessary to look for the specific pulse corresponding to the chosen droplet generator. Flexible pulse form generation appears to be more suitable than simple pulse forms for the generation of such droplets.://000255648800006iISI Document Delivery No.: 297WT Times Cited: 0 Cited Reference Count: 23 Riefler, Norbert Wriedt, Thomas 0934-0866Part.

More recent applications include laser cleaning [2], scanning near-field optical microscopy (SNOM) [3] and plasmon resonances effects in surface-enhanced Raman spectroscopy (SERS) [4]. Several studies have addressed this scattering problem using different methods. Simplified theoretical models have been developed on the basis of Lorenz-Mie theory and Fresnel surface reflection [5–8]. A coupled-dipole algorithm has been employed by Taubenblatt and Tran [9] and Nebeker et al. [10] using a three-dimensional array of dipoles to model a feature shape and the Sommerfeld integrals to describe the interaction between a dipole and a surface. The theoretical aspects of the coupled-dipole model has been fully outlined by R. Schmehl [11]. A model based on the discrete source method has been given by Eremin and Orlov [12,13], whereas the transmission conditions at the interface are satisfied analytically and the fields of discrete sources are derived by using the Green tensor for a plane surface. More details on computational methods and experimental results can be found in a book edited by Moreno and Gonzales [14].-http://dx.doi.org/10.1007/978-3-540-48546-9_410.1007/978-3-540-48546-9_4|?oWriedt, T.

Ctr Electromagnet Theory Applicat, Res Lab Elect Mar 26-29^Since its invention in the mid of eighties [1] Total Internal Reflection Microscopy (TIRM) has proven to be an effective technique to measure weak interactions between spherical colloidal particles and surfaces with a resolution of a few femtonewton. It is a single particle evanescent light scattering technique. In an experimental setup a laser beam is coupled into a prism and hits the glass-water interface with an angle slightly above the critical angle of total internal reflection. This generates an evanescent field near the interface that decays in the lower refractive index medium (water) with a characteristic penetration depth which depends on the angle of incidence. A colloidal particle that is dispersed in the medium will scatter light from the evanescent wave if it is in the vicinity of the surface. By registering a scattered intensity it is possible to deduce the particle-substrate distance. Compared to other methods for measure particle wall interactions like the surface force apparatus or the atomic force microscopy where a colloidal particle is attached to the tip, TIRM is the most sensitive technique because thermal fluctuations where limit the other methods in their resolution are exploited to determine the interaction potential. In this way forces in the order of a few femtonewton can be detected. TIRM has proven to be a valuable tool for the precise measurement of weak colloidal interactions as double layer forces, van der Waals forces, magnetic interactions and depletion forces. Review on TIRM can be found for example in [2,3]. To compare experimental results with results of mathematical modeling an effective light scattering method is needed. For this purpose the Discrete Sources Method (DSM) has been chosen. The DSM is a well-known method for light scattering analysis, which has recently been applied for evanescent wave scattering [4].://000241313400093jISI Document Delivery No.: BFD87 Times Cited: 0 Cited Reference Count: 7 Eremina, E.

M.Antalya, TurkeyBegell House, IncInt Ctr, Heat Mass, Transfer Nov 03-07In the recent years increasing activities in the field of Liquid/Liquid-Extraction (LLE) Process modeling could be observed. One prerequisite for further success in this field of research is the determination of process data like droplet size and velocity or mass transfer rates as a result of single-droplet experiments or determination from technical apparatus. Within this study the innovative laseroptical measurement techniques, Phase-Doppler-Anemometry (PDA) and Rainbow Refractometry (RBR), offering the capability of fast and reliable data acquisition will be adopted to the characterization of droplets in ternary liquid two-phase systems.://000171844700044IISI Document Delivery No.: BT06K Times Cited: 0 Cited Reference Count: 11 1-56700-111-4ISI:000171844700044English{~7$Manasse, U.

Bauckhage, K.1993Reconstruction of real size distributions hidden in Phase-Doppler Anemometry results obtained from droplets of inhomogeneous liquids84-90#Congress on Optical Particle SizingYokohama, JapanVch Publishers IncAugReal process fluids such as emulsions and suspensions are optically absorbent as well as inhomogeneous. Using phase-Doppler anemometry (PDA) for investigating the spray cone, the inhomogeneities have led to incomprehensible size distributions. In this paper, solutions of instant coffee and condensed milk, representing typical process fluids, were chosen for PDA measurements in comparison with PDA applied to water droplets with the same atomization process in order to clarify the reasons for the measured broad size distributions. By applying PDA to monodisperse droplets and to ''monodisperse'' and real polydisperse sprays consisting of such fluids, it is shown how the measured size distributions arise. Based on this knowledge, the real size distributions are reconstructed and compared with that of water atomization. Therefore, PDA can in future also be applied to real process fluids, and process control, based on the information provided by PDA, is coming nearer.://A1994NJ18600010HISI Document Delivery No.: NJ186 Times Cited: 6 Cited Reference Count: 8ISI:A1994NJ18600010English&|7.Göbel, G.

P.Kusadasi, TurkeyBegell House, IncLInt Ctr, Heat Mass Transfer, Sci Technol Council Turkey, Metu Univ Kentucky,JulThe light scattering properties of optically inhomogeneous spherical particles are studied by means of a phase resolved 3-dimensional Monte Carlo simulation. This is equivalent to a radiative transfer process in a participating medium with spherical boundaries. For zero concentration of inhomogenities we obtain the undisturbed scattering distribution of the coherent light with its size-dominated oscillating structure. With increasing optical depth of the scattering medium this interference structure is disturbed by multiple scattering within the particle and the corresponding loss of coherence. For large optical depth the Schoenberg result for a sphere with a Lambert surface is obtained. Thus it is possible to quantify the influence of size and concentration of a fine dispersed phase inside a spherical droplet onto the light scattering properties of an inhomogeneous macroscopical particle. This is of importance for the application of various optical particle sizing techniques on media, that contain fine dispersed substances.>http://diogenes.iwt.uni-bremen.de/vt/laser/papers/kusadasi.pdfIISI Document Delivery No.: BN04D Times Cited: 0 Cited Reference Count: 18 1-567-00116-5ISI:000080479900023English[|7.Manasse, U.

In this work the effect of extreme transmission through the hole in the evanescent wave's area is in focus. The discrete sources method has been applied to analyse the spectral characteristics of light scattered by a cylindrical nanohole in a noble-metal film on a prism surface. The influence of the wavelength, incident angle, film materials and hole's filling on the scattering characteristics has been investigated.

We considered RBCs with diameters up to 8 mu m (size parameter up to 38), relative refractive indices 1.03 and 1.06, and two different orientations. The agreement in the angle-resolved S-11 element of the Mueller matrix obtained by these methods is generally good, but it deteriorates with increasing scattering angle, diameter and refractive index of a RBC. Based on the DDA simulations with very fine discretization (up to 93 dipoles per wavelength) for a single RBC, we attributed most of the disagreement to the DSM, which results contain high-frequency ripples. For a single orientation of a RBC the DDA is comparable to or faster than the DSM. However, the relation is reversed when a set of particle orientations need to be simulated at once. Moreover, the DSM requires about an order of magnitude less computer memory. At present, application of the DSM for massive calculation of light scattering patterns of RBCs is hampered by its limitations in size parameter of a RBC due to the high number of harmonics used for calculations.

Wriedt, T.2011Improving the numerical stability of T-matrix light scattering calculations for extreme particle shapes using the nullfield method with discrete sources 1679-16869Journal of Quantitative Spectroscopy & Radiative Transfer11211JulOver the years the T-matrix method based on the nullfield method established itself as a fast and reliable approach for light scattering simulation. Compared to other programs based on discrete dipole approximation or finite different time domain, programs calculating the T-matrix usually are faster. Unlike the Mie theory the underlying nullfield method can also be used for non-spherical particles, but one will observe a limited numerical stability in this case. Using an advanced approach, the nullfield method with discrete sources, we would like to demonstrate how to improve the numerical stability and to get results also for particles with extreme shapes like fibers or discs with high aspect ratios or concavities. In this paper we intentionally keep the mathematical part rather small, instead we focus on more general explanations for users of corresponding computer programs by outlining basic ideas and concepts.

Nature 1998; 391, 667) through subwavelength holes array in noble metal screen is used for multiple practical applications in nanooptics and biophotonics. In this paper the Extreme Transmission Effect (Eremina et al. Opt. Comm. 2008; 281, 3581) in the noble metal film deposited on a glass prism in the evanescent wave's area is in focus. The Discrete Sources Method (DSM) has been adjusted to calculate the polarized light scattering by an axially symmetric inclusion located in a film deposited on a glass prism. We extended the DSM for the evaluation of the Scattering Cross-Section in the prism domain. It has been shown that the maximum value of the Reflection Cross-Section appears at the same incident angle as for the Transmission Cross-Section. It has been demonstrated that the Reflection Cross-Section can exceed the Transmission Cross-Section under certain circumstances. Analysis of the correlation between the Plasmon Resonance in the gold film and the Extreme Scattering Effect demonstrates that the Plasmon Resonance plays an important but not the exclusive role in the appearance of the Extreme Scattering Effect.

Schmidt, V. Wriedt, T. Eremin, Y.2011TImplementation and investigation of iterative solvers in the Discrete Sources Method 1697-17049Journal of Quantitative Spectroscopy & Radiative Transfer11211JulThe implementation of iterative methods as solvers for the Discrete Sources Method (DSM) is presented. In this method, light scattering computation linear systems with dense and relative small matrices are generated. The linear systems are traditionally solved using the QR-decomposition method. For large particles or particles with extreme geometries even this commonly stable solver can fail. In these cases, we expect that iterative methods can provide a satisfying solution nevertheless. We will present our investigation in two consecutive papers. Here, we study four different iterative solvers (RGMRES, BiCGStab, BiCGStab(l), and MinRes) considering the performance and the accuracy for typical light scattering problems. Using these iterative methods we increased the quality of a solution, especially for oblate spheroids with a higher aspect ratio. Preconditioning technique is considered in the following paper.

This semi-analytical method is used for light scattering computations by particles in the Mie scattering regime. Its numerical schema includes a linear least-squares problem commonly solved using the QR decomposition method. This could be the subject of numerical difficulties and instabilities for very large particles or particles with extreme geometry. In these cases, we showed that iterative methods with preconditioning techniques can provide a satisfying solution. In our previous paper, we studied four different iterative solvers (RGMRES, BiCGStab, BiCGStab(l), and MinRes) considering the performance and the accuracy of a solution. Here, we study several preconditioning techniques for the MinRes method for a variety of oblate and prolate spheroidal particles of different size and geometrical aspect ratio. Using preconditioning techniques we highly accelerated the iterative process especially for particles with a higher aspect ratio. Crown Copyright (C) 2011 Published by Elsevier Ltd.

In this paper the Discrete Sources Method has been applied to model different measuring schemes for TIRM to find the most appropriate one for the determination of the distance between a particle and the filmed surface. It has been found that the placing of a light collector beneath the prism gives a considerable advantage compared with a conventional TIRM design, where the collector is situated above the surface.

Investigation of light scattered by nanostructures by means of computer simulation seems to be a reliable tool for investigation of the properties and functional abilities of nanostructures. In particular, nano-features embedded in layered structures are of growing interest for many practical applications. Mathematical modeling of light scattering allows us to predict functional properties and behavior of nanostructures prior to their fabrication. This helps to reduce manufacturing and experimental costs. In the present paper, the Discrete Sources Method (DSM) is used as a tool of computational nano-optics. Mathematical models based on DSM are used for several practical applications. We are going to demonstrate that the computer simulation analysis allows not only prediction and investigation of the system properties, but can help in development and design of new setups.!://WOS:000288739800004*Eremina, Elena Eremin, Yuri Wriedt, Thomas 0950-0340WOS:00028873980000410.1080/0950!F|?+Karamehmedovic, M.
