A frequency selective surface (FSS) is a metallic periodic structure with frequency selective properties. Depending upon design, it may be low-pass, high-pass, band-pass, band-stop filter.
频率选择表面(FSS)是具有选择频率功能的一块金属周期结构,它可以被设计成低通、高通、带通、带阻滤波器。
In addition, the stop-band rejection can be further increased by using elliptic filter function which has limited frequency transmission zeros.
另外,在函数类型上使用椭圆函数型,使带外出现有限频率传输零点,进一步提高了带外抑制能力。
