Abstract

This paper presents a new metamaterial, based on SRR structure and systematically investigate the various properties of the metamaterial structure. The resonant frequency of the proposed metamaterial structure is first estimated using its equivalent circuit model and the estimated value thus obtained is then compared with the values obtained by High Frequency Structure Simulator (HFSS) simulations. The negative refraction in the unit cell is demonstrated by estimating the negative ε and negative µ on placing the unit cell in a waveguide with well defined PEC/PMC boundary conditions. Finally the unit cells are combined to form linear 2D array topology.
