Variable-reflection-angle meta-surface using double-layered patch-type FSS

Abstract

This paper describes a variable-reflection-angle meta-surface that can control a scattering pattern by sliding one layer of a double-layered frequency selective surface. A reflection angle within a range of approximately 2° to 35° is obtained in the proposed structure according to the unit cell analysis of the meta-surface. A scattering pattern is calculated by FDTD analysis, and the peaks are in good agreement with the range.
