摘要
应用谱分析技术推导出单色电磁波的入射功率以及它通过栅网后的反射功率及透射功率,并将它们应用到高斯波束入射时的情形,得到高斯波束的入射功率以及它通过栅网后的反射功率及透射功率公式,其结果与基本平面波(EPWS)叠加法得到的一致。文中还具体计算了高斯波束入射到纯导体和实际栅网的反射功率系数及透射功率系数,并且与平面波入射时的情形进行了比较。
In this paper, the general power forms for an incident monochromatic electromagnetic beam and its reflected and transmitted beams on wire grids are derived with the spectral representation techniques. The reflection and transmission powers of a Gaussian beam by wire grids are presented with these forms and compared with the results acquired from Fourier transform method by the sum over a set of elementary plane waves （EPWs）. The numerical results with a perfectly conducting and an actual cylindrical wire grid are presented and compared with those of a plane wave incidence.
