Linear to Circular Asymmetric Transmission based on Chiral Metasurface
In this paper a dual band chiral metasurface is presented for linear to circular polarization conversion. The structure consists of two resonators and the unit cell is rotated 90° to obtain a chiral geometry. The circular polarization is achieved when co- and cross- transmission coefficients have equal magnitudes with 90° phase difference. The axial ratio is below 3dB within two frequency bands ranging from 5.84GHz-5.99GHz and 7.80GHz-8.09GHz showing circular polarization conversion.
