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)
