摘要

复射线理论为高频电磁波在各种复杂环境中的传播和散射提供了一种简便而有效的分析方法。本文讨论了自由空间的复射线场

在单层界面上的反射和折射

通过分层媒质的多次反射和传输

在乎界面上的全反射和临界反射

在结构边缘上的绕射

复射线展开和叠加

以及用复射线法计算目标的雷达截面等。文中还给出了某些数值计算结果。

Abstract

The complex ray theory provides a simple and useful approach to analyze 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.
