ABSTRACT:
This paper adumbrates novel metamaterials (MTMs) named ā€˜Cā€™ shaped Pair (CSP) and Closed Ring Pair (CRP). Ansoft HFSS has been used to design and analyse the CSP MTM having FR4_epoxy (er=4.4) as substrate material and CRP MTM having Mylar (er=2.89) as substrate material. Electric and Magnetic properties of MTMs have been used to mathematically demonstrate the negative permeability and permittivity region. Nicolson Ross Wier (NRW) method has been used to retrieve the material parameters from transmission and reflection coefficient. Nearly 5% deviation has been obtained between the results from Finite Element Method (FEM) based Ansoft HFSS and transmission line theory based quasi-static regime.
