An invariant imbedding T matrix approach to electromagnetic scattering
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 twoterm recurrence relation which can be solved numerically for the T matrix. The limiting form of this recurrence relation is a firstorder nonlinear differential equation that is identical in form to the quantum mechanical Calogero equation. The results of several test calculations are presented.
