Impedance Modelling of Metamaterial Structure Based on Double Quad-Square Split Ring Resonator (Dqs-Srr) at 2.4 GHZ and 7.4 GHZ

Abstract

This paper represents the impedance modelling of metamaterial structure based on Double Quad-Square Split ring Resonator (DQS-SRR). The impedance was modelled for DQS-SRR design structures. This structure simulation works had been done in CST Microwave Studio simulation software while the impedance was modelled by using polynomial type in Matlab for resistance, R, and reactance, X, of the impedance. The modelling of the impedance was based on the length of U-slot arm (Larm) and the width of U-slot arm gap (Wgap) of the DQS-SRR design structure .The impedances were divided into the certain ranges of length and width for dimensions of DQS-SRR so that an accurate impedance modelling was produced. The impedance was modelled for the resonant frequency of 2.4 GHz and 7.4 GHz. This DQS-SRR structure has potential application to improve of pyramidal microwave absorber to for certain frequency range.
