Realization of a Dual Transmission Band Conjugate Omega Shaped Metamaterial
In this article we propose a new conjugate omega shaped structure for realization of left hand material. This new metamaterial (MTM) is designed and simulated using CST MWS. The effective permittivity permeability are extracted from the transmission reflection data obtained by normal incident on the purposed structure. It is shown the purposed MTM exhibits DNG material property and negative refractive index in dual transmission band with wider band in frequency ranges from 3.35-6.37GHz and 12.53-16.7GHZ. The conjugate omegas structures are pseudo-chiral in nature, where both electric magnetic polarization are due to induced electric and magnetic fields.
Keywords: MTM, refractive index, Ω shaped, electromagnetic propagation
