Design and Simulation of Metamaterial based Resonant Absorber

Ravia Puri [2] | Dr. Ruchi Singla

Abstract: A Resonant absorber using metamaterial structure is designed which is used to minimize the reflection and transmission of light and increasing absorption. This work includes design and simulation results of a metamaterial structure which act as resonant absorber. This design provides absorption of electromagnetic wave at resonant frequency of 10.5 GHz. From transmission line theory resonant absorbers which depends on the material’s way to interact with wave at particular frequency. Resonant absorbers are also called as quarter wavelength absorbers. Absorber design is an impedance match problem which can be achieved by attaining condition of resonance. MTM with its strong EM responses is used for designing a resonant absorber. MTM is material with negative value of permeability and permittivity made up of periodic array of electric and magnetic inclusion. Apart from various applications of MTM, it is best suited to be used as absorber. Absorption of 74 % is achieved at 10.5 GHz and reflection is reduced to 20 % at resonance frequency of 10.5 GHz. The use of silver as material for designing cut wire effected the transmission and transmission is only 6 %.
