Abstract

In this paper, we discuss the comparative study of rectangular SRR, circular SRR and SRR Array for multi-band metamaterial applications. The value of each resonance frequency can be adapted by changing design parameters such as metal widths and gap distances for each ring as well as ring-to-ring separations. The suggested SRR and SRR Array structure is simulated using CST Microwave Studio. The material parameters of the resulting rectangular, circular SRR and SRR Array type metamaterials are estimated by a Nicolson- Ross-Weir (NRW) retrieval algorithm. Since a metamaterial is a manmade material which is having negative permittivity and permeability, it can be regarded as an artificial medium with negative index of refraction. Negative refraction was determined by a Snell’s Law. The split ring resonator acts as an artificial magnetic dipole. The gap between inner and outer ring acts as a capacitor while the rings themselves act as an inductor, resulting in an LC resonant circuit and SRR Array gives the fine resonance frequency.
