Numerical Solution of 2D and 3D Scattering Problems on a Dielectric Body by a Method of Optimum Simple Iteration

摘要

A numerical solution of volume integral equation of scattering by dielectric body in vector 2D and 3D cases in low-frequency and resonant region is under investigation. Examples of application of the method of optimal simple iteration (MOSI) are present. Efficient numerical technique is based on the spectral properties of the integral operator. The accuracy of the first approximation of the optimal series in vector 2D case and near-resonant region in comparison with so-called the Born approximation and with the solution of MOSI is under consideration.
