Frequency selective surface (FSS) is a robustly studied topic of electromagnetic (EM) science, which are two-dimensional periodic structures having planar metallic array elements (patch or apertures) on a dielectric substrate, exhibiting transmission and reflection at certain resonant frequency [2].
FSSs are usually designed by periodic metallic arrays of elements on a dielectric substrate and exhibit transmission and reflection characteristics at a certain resonant frequency.
Mushroom structures are the class of FSSs that is designed to resonate at low frequencies as the distance between metal array element and a metal plane creates an inductive effect at microwave regime.
FSSs are usually designed by periodic metallic arrays of elements on a dielectric substrate.
[49], in which small metallic arrays are periodically printed in patch layer (capacitive mesh) on one side of a dielectric substrate.
