摘要
应用模匹配方法,研究了关于中心层面对称的双层频率选择表面(FSS)的传输特性。讨论了各介质层厚度改变对频率选择表面频响特性的影响,指出通过修正双层FSS的有关介质参数,可以有效地改善传输带宽的稳定性并缩小传输曲线谐振区的深沟。
A symmetric double-layer frequency selective surface is studied by adopting the symmetric and anti-symmetric excitation method. Transmission properties of the structure are discussed for different dielectric parameters of the structure. It is shown that the frequency response of the structure can be great by improved by choosing suitable dielectric parameters of the covering and coating layers.
