Multiple-Bounce Scattering from Electrically Large Objects: Is Ray Optics Sufficient?

Abstract

Application of Geometrical Optics to calculation of multiple-bounce contributions to electromagnetic scattering from electrically large faceted objects is examined. It is shown that ray-based approaches may lead to significant errors in describing the interaction between distant facets and the use of Physical Optics might be necessary to reliably predict the scattered fields with well-pronounced multiple-bounce contributions.
