Abstract

The Iterative Physical Optics (IPO) method, which was originally developed for computing electromagnetic scattering from cavities and later extended to more general geometries, has been shown to be accurate for many types of targets. In this paper, we examine the IPO method from the standpoint of its potential use for engineering electromagnetic scattering predictions. Using an IPO engineering computer code that we developed recently as a basis for discussion, we describe the problems encountered, the techniques we used for overcoming those problems, and the effectiveness of those techniques. We also show comparisons of our IPO results with method of moments and ray-based methods.
