Abstract

Scattering of an arbitrarily focused electromagnetic Gaussian beam by a cluster consisting of a chain of axisymmetric microparticles is presented. The illustrated technique in this work combines the plane-waves spectrum method and a modification of the cluster T-matrix method. This combination provides a powerful tool to calculate the scattered fields from a cluster of different shaped particles illuminated with an arbitrarily incident electromagnetic wave. The presented technique is used to calculate the scattering matrix elements of different cases of a cluster illuminated with different beam focusing.
