周期性Y形缝隙阵列和多层介质复合结构的分析

Analysis on Combined Periodic Y Slot Array withMultiLayer Dielectric Superstrate and Substrate

应用模匹配法分析了周期性Ｙ形缝隙阵列和多层介质复合ＦＳＳ结构的频率响应。重点研究了不同介质加载方式和介质参数对ＦＳＳ结构传输特性的影响。研究发现，在周期阵列的两侧同时加载相同的介质层，可以极大地改善其传输特性。

A modal analysis is presented for a frequencyselective surface, consisting of a periodic Y slot array embeded on the multiplelayer dielectric superstrate and substrate. The effect of dielectric parameters on transmission properties of the Y slot array is particularly studied. We show that by loading dielectric layers on both sides of the slot array, the transmission property of the array can be greatly improved.
