摘要：

In this paper, a dual-band 90 polarization rotator is proposed by using chiral metamaterial composed of two pairs of two-layered twisted split ring resonators (SRRs) in each unit. When an x-polarized wave incidents on this polarization rotator, the experimental result shows that the electric field is transformed into its cross-polarization at the frequency of 13.47 GHz and 15.39 GHz due to the transverse magnetic dipole coupling, and its transmission coefficients are -0.37 dB and -1.05 dB at these two resonances, respectively. The surface current distributions are calculated to explain original physics. (C) 2012 Elsevier B.V. All rights reserved.
