论文摘要
给出了一种通过不规则的表面和空间变化的阻抗评估电磁散射的方法。这使用操作员扩展在阻抗变化方面，并允许检查其效果以及由粗糙表面散射的场的修饰。对于固定的粗糙表面和随机变化的阻抗，为散射场本身而得出表达式，以及对于有效阻抗条件形式的平坦和粗糙表面的阻抗变化的相干场。
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.
