Parametric studies on left-handed metamaterial consist of modified split-ring resonator and capacitance loaded strip

Abstract

This paper describes a new structure of left-handed metamaterial (LHM) based on parametric studies using Computer Simulation Technology (CST) software. The LHM structure is a combination of the modified square rectangular split ring (MSRR) and the capacitance loaded strip (CLS). In this paper, the parametric studies are used to see the effect of frequency and the negative value range of permeability (μ r ) and permittivity (ε r ) toward changes of LHM parameters. The changes in the dimension of MSSR and CLS affect the S 11 and S 21 of the LHM structure which will affect the values of permeability and permittivity. The values of permeability and permittivity were extracted from the reflection and transmission coefficient data. The studies proved that the LHM structure can be designed within the frequency range of interest.
