Determination of transition matrices for inhomogeneous dielectric bodies by a wave propagator method
(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) - A method for determining transition matrices for inhomogeneous dielectric
