Effcient analysis of electromagnetic scattering problem using proper orthogonal decomposition

Abstract

This paper describes a novel approach for e±ciently solving electromagnetic (EM) scattering problems using proper orthogonal decomposition (POD). As a proof of concept and demonstration of how to use the POD to solve EM scattering problems, two ways of implementa- tion of the POD procedure have been proposed and realized for calculating EM scattering from 2D PEC targets using electric field integral equation (EFIE) for TE polarization and magnetic field integral equation (MFIE) for TM polarization. Preliminary results obtained show that the POD is quite accurate for reconstructing backscatter patterns over wide range of frequencies and angles of interest based on the given snapshots.
