Systematic Analysis on the Optical Properties of Chiral Metamaterial Slab for Microwave Polarization Control
Keywords:
Chirality, EM filter metamaterial, polarization controlAbstract
Theoretical and numerical of investigation of the chiral slab exhibiting polarization rotation is presented in detail. The effects of the chirality, thickness of medium, dielectric constant, and incident angle are analyzed in order to display the characteristic features of the chiral slab both for TE and TM incident waves. The chiral slab then is realized by using a full wave EM simulation software in order to validate the numerical results in which the numerical and simulation results are in good agreement with each other. Different than the other studies existing in literature, the proposed model shows optimum results for wide frequency band by using small chirality which is sufficient for polarization rotation. From the results, it is observed that the proposed system and its realization can be effectively used as a polarization converter and EM filters at some frequencies.
