线源激励二维理想导体角反射器辐射场严格解

Rigorous Solution of the Electromagnetic Radiated Field of a Two dimensional Perfectly Conducting Dihedral Corner Reflector Illuminated by a Line Source

采用模式匹配法，对平行电流丝或磁流丝作用下二维理想导体角反射器的电磁辐射进行了严格地电磁场分析。推导出了以散射场展开系数为未知量的矩阵方程，给出了计算实例，其中张角为１８０°（即平板）的计算结果与文献［４］的结果是一致的。

The electromagnetic radiation of a two dimensional perfectly conducting dihedral corner reflector illuminated by a parallel line source are analysed rigorously by using the mode matching technique. A system of linear equations whose unknowns are the scattered field expansion coefficients are developed, they are solved to obtain the scattered field expansion coefficients by the computer, thereby the radiated field are calculated. The numerical examples are given in this paper, in which the computed results of a opening angle =180° (that is the strip) are identical to the corresponding results in reference.
