Abstract

In this paper, the optical properties of the novel windmill-shaped chiral metamaterial (CMM) with low ellipticity have been studied numerically in THz band. The dispersionless optical activity can be achieved in a wide frequency range (i.e. from 1.7 THz to 2.7 THz). The dependence of CMM’s optical properties on the structural parameters is studied systematically and the frequency range of low ellipticity can be controlled dynamically through adjusting the width of the metal. The excitation mechanism of optical activity based on the current distribution is also analyzed in detail.
