Comparative analysis of resonance characteristics single sided SRR type metamaterials for varying gap size

This paper presents a analysis of planar double-negative (DNG) metamaterial unit cell, named split ring resonator (SRR), to obtain better miniaturization at microwave frequencies for a given physical cell size. In this study, electromagnetic transmission characteristics of square split ring resonator and circular split ring resonator of same area are investigated in a comparative manner for varying values of gap size of both type ring resonators.
