Abstract
An ultrathin dual-band planar chiral metamaterial (CMM) with giant optical activity using Fermat’s Spiral structure (FSs) was proposed, which could yield a near polarization angle independent 90° rotation characteristic. The proposed CMM can convert an incident linear polarization (y-/x-polarized) wave into its cross-polarization (x-/y-polarized) or experience a near 90° polarization rotation at 4.67 and 8.51 GHz, respectively. The experiment results are in agreement well with numerical simulation. The surface current distributions of unit-cell structure of the proposed CMM were analyzed to illustrate the physics mechanism of this giant optical activity with 90° polarization rotation. Good performances and compact design of the CMM suggest a promising application in 90° polarization rotator that need to be integrated with other compact devices.
