Abstract
This paper presents a composite artificial electromagnetic structure that couples aplasma photonic crystal(PPC) with frequency selective surface (FSS). Plasma photonic crystals, as an artificial electromagnetic structure, have the effects of photon band gap and photon locality, but their cut-off frequency is affected by their characteristic scale, so we couple another artificial electromagnetic structure FSS, and expect it to have better electromagnetic properties and tuning capabilities. The S- parameters of this coupled artificial electromagnetic structure in the 6-18GHz frequency band were simulated and measured in a microwave darkroom, which proved that the structure has excellent electromagnetic characteristics.
