摘要: 應(yīng)用模匹配方法,研究了關(guān)于中心層面對(duì)稱(chēng)的雙層頻率選擇表面(FSS)的傳輸特性。討論了各介質(zhì)層厚度改變對(duì)頻率選擇表面頻響特性的影響,指出通過(guò)修正雙層FSS的有關(guān)介質(zhì)參數(shù),可以有效地改善傳輸帶寬的穩(wěn)定性并縮小傳輸曲線諧振區(qū)的深溝。Abstract: 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.
