摘要
采用模量匹配法研究了一维周期金属栅的电磁特性，获得了各场量的表示式．反射系数的计算结果表明，对于一定波长范围的电磁波，通过适当选择微结构的几何参数和反射系数可以得到很大的抑制。
The EM characteristics of one dimensional periodic metal grid are studied by mode matching and the expressions for all field quantities are derived. The computation of the reflectivity of EM waves by the grid shows that the reflection can be suppressed significantly ( R min =0.05) for a certain range of wavelength of EM waves by choosing suitable periodic structural parameters. However, such a structure will still exhibit a high reflectivity for the IR ray.
