T-Matrix Method for complex scattering problems

The well-known T-matrix method for light scattering computation is of advantage because in a computed T-matrix all information on the scattering process is contained.
With clusters of fibres the circumscribed spheres of the constituent fibres would overlap and it would not be possible to directly compute the T-matrix and thus scattering by
such a cluster using the standard multiple scattering approach.
We developed a decompositioning method of the original scattering problem into a number of subscatterers and computing an approximation of original scattering problem using a multiple scattering approach combining the T-matrices of all subscatterers.
