Abstract
Development of chiral metamaterial (CMM) structures in order to achieve miniaturized CMMs and dual-band CMMs are aimed in this paper. In achieving the first purpose, two general ideas are proposed: using dendritic fractal geometry, and using wideband antenna designs. Based on these methods, some miniaturized CMM structures are designed. Afterwards, a novel dual-band CMM structure is designed and fabricated. The results show that the proposed structure exhibits giant optical activity and negative refractive indices for the right and left circularly polarized waves (RCP and LCP) in two adjustable frequency bands.
