Extension of moment-method solutions to vector scattering by three-dimensional non-linear dielectric objects in free space
Authors:Salvatore Caorsi  Andrea Massa  Matteo Pastorino
Abstract:In this paper, we explore the possibility of applying the moment method to determine the electromagnetic field distributions inside three-dimensional bounded non-linear dielectric objects of arbitrary shapes. The 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 electric field. Preliminary results of some numerical simulations are reported.
Keywords:moment method  non-linear electromagnetics  scattering  dielectrics
