Effect of miniaturization of the unit cell of a meta-surface using double-layered FSS

Abstract

This paper proposes a meta-surface for a miniaturized unit cell that consists of a double-layered Frequency Selective Surface (FSS) and the ground plane. Additional miniaturization of the unit cell is achieved by sliding one layer of the double-layered FSS in the polarization direction of an incident wave. Moreover, the unit cell becomes smaller than half the size of a conventional single-layered meta-surface by using the double-layered FSS.
