Design of Metamaterial Electromagnetic Wave Absorber Using Square Metallic Pattern Periodic Array Sheet

Abstract

In this study, the authors designed metamaterial electromagnetic (EM) wave absorbers using a square metallic pattern periodic array sheet with isotropic reflection property and dielectric material. Using measurement in free space, we confirmed that the resonant frequency and the amount of EM wave absorption can be controlled by modifying the structural parameters of the metallic pattern periodic array sheet.
