摘要

给出了一种评估具有空间变化阻抗的不规则表面的电磁散射的方法。这使用了关于阻抗变化的算子展开，并允许检查其影响以及由此产生的粗糙表面散射场的修改。对于固定的粗糙表面和随机变化的阻抗，导出了散射场本身的表达式，以及以有效阻抗条件形式的平坦和粗糙表面的相干场关于阻抗变化的表达式。

RANDOM SCATTERING BY ROUGH SURFACES WITH SPATIALLY VARYING IMPEDANCE

A method is given for evaluating electromagnetic scattering by an irregular surface with spatially-varying impedance. This uses an operator expansion with respect to impedance variation and allows examination of its effects and the resulting modification of the field scattered by the rough surface. For a fixed rough surface and randomly varying impedance, expressions are derived for the scattered field itself, and for the coherent field with respect to impedance variation for both flat and rough surfaces in the form of effective impedance conditions.
