Abstract:

A new method for calculating electromagnetic scattering from an arbitrary shaped, inhomogeneous, dielectric object is developed. The method is based on an invariant imbedding procedure for computing the T matrix that was originally developed to solve quantum mechanical scattering problems. The final outcome of this approach is a two-term recurrence relation which can be solved numerically for the T matrix. The limiting form of this recurrence relation is a first-order nonlinear differential equation that is identical in form to the quantum mechanical Calogero equation. The results of several test calculations are also presented. Keywords include Electromagnetic waves, Light scattering, Nonspherical dielectric particles, Invariant imbedding. rh
