Application of Complex Ray Theory in EM Scattering and RCS Analysis

Abstract

The complex ray theory provides a simple and useful approach for the analysis of the propagation and scattering of HF EM waves in various complicated environments. This paper deals with complex ray fields in free space, reflection and refraction at a single interface, multiple reflections and transmission through a layered medium, total reflection and critical reflection at a planar interface, diffraction at an edge, complex ray expansion and superposition, as well as RCS calculation by complex ray method. In addition, some numerical results are given. Keywords: Electromagnetic wave propagation; Electromagnetic wave reflections; High frequency.
