摘　　要：针对含基底的单屏频率选择表面(FSS)在电磁波倾斜入射时中心频点漂移过大,透过率下降迅速的问题,利用谱域分析方法对电介质层匹配方式作了详细的研究,提出了一种对称夹层的匹配方法。分析结果表明,对于大范围角度入射的电磁波,该方法能够在不改变原基底特性的情况下,优化FSS的传输特性。For the application of the single layer Frequency selective surface （FSS） with substrate, the center frequency will drift and the transmission coefficient will drop with the steering of the incident angle. A symmetrical sandwich dielectric matching method is presented and studied by the spectral-domain approach in this paper. As a result of the numerical analysis, it is shown that the frequency response of the FSS structure is proved by using the proposed method over a wide range of incidence angles without altering the properties of substrate.
