Determination of transition matrices for inhomogeneous dielectric bodies by a wave propagator method

Karlsson, Anders LU (1999) In Progress in Electromagnetics Research PIER 23. p.315-335
Abstract
A method for determining transition matrices for inhomogeneous dielectric

shells is presented. The source can be either inside or outside the shell. The

method is based upon expansions of the electric and magnetic fields in vector

spherical harmonics. The expansion coefficients in the shell satisfy a system

of linear ordinary differential equations in the radial direction. The expansion

coefficients for the incident and scattered fields are related via transition

matrices, defined in the same way as in the T-matrix or null-field method.

Numerical examples showexcellen t agreement with results obtained by the

T-matrix method. Numerically the method is particularly... (More)
