Hybrid Metamaterial Absorber based on the Combination of Plasmonic Structure and Magentic Absorber

Abstract

Inspired by efficient spoof surface plasmonic polarization (SSPP), the dispersion characteristic has recently been demonstrated to be flexibly controlled in plasmonic structure. Inspired by this, a comprehensive scheme of hybrid metamaterial absorber (MA) based on the combination of plasmonic absorbing structure (PAS) and magnetic absorber has been proposed which can achieve extremely broadband absorption with the efficiency over 90% during the frequency band from 4.2GHz to 40.0GHz. The proposed concept provides an effective scheme with the simultaneous capability of broadband absorption, polarization insensitivity as well as lightweight characteristic, promising an extensive range of applications in electromagnetic compatibility/shielding.
