Design of electromagnetic wave absorber using periodic structure and equivalent circuit-based analysis

In this paper, new electromagnetic wave absorber based on periodic structure and equivalent circuit-based analysis are presented. The proposed structure shows a broadband characteristic, and its bandwidth is improved by generating additional resonance through the reasonable approach based on impedance analysis and equivalent circuit. For the verification of this approach, the functionality of the absorber, the proposed technique, and the experimental results are demonstrated along with analytical and computational results.
