Plasma technology is widely used in the electromagnetic field. In this work, a novel composite frequency selection (CFS) device composed of plasma and metallic periodic structure is proposed. This paper demonstrates the reflection coefficient of the proposed CFS at 12-18 GHz. The dispersion of absorption effect in the frequency domain is also mentioned. A simulation result of the electric field distribution of CFS device is presented to give a tentative explanation.
