EXTENSION OF MOMENT-METHOD SOLUTIONS TO VECTOR SCATTERING BY 3-DIMENSIONAL NONLINEAR DIELECTRIC OBJECTS IN FREE-SPACE

In this paper. we explore the possibility of applying the moment metho d to determine the electromagnetic field distributions inside three-di mensional bounded non-linear dielectric objects of arbitrary shapes. T he moment method has usually been employed to solve linear scattering problems. We start with an integral equation formulation, and derive a non-linear system of algebraic equations that allows us to obtain an approximate solution for the harmonic vector components of the electri c field. Preliminary results of some numerical simulations are reporte d.
