â¢Scattering of a focused beam by a cluster of axisymmetric particles is investigated.â¢The beam is modeled using angular spectrum of plane waves method.â¢The T-matrix method is modified to solve such a difficult problem..â¢Different clusters and incident beams are considered to compute the scattering matrix.
Scattering of an arbitrarily focused electromagnetic Gaussian beam by a chain cluster consisting of axisymmetric particles is presented. The illustrated technique in this paper combines the plane-waves spectrum method and the cluster T-matrix calculation technique. This combination provides a powerful mathematical and numerical tool to solve such types of scattering problems. Computed results are shown for different particles shapes in the cluster and for different beam focusing.
