A Broadband Transmission Metasurface with Polarization-Transforming Functionality
MetadataShow full item record
A transmission metasurface with polarization-transforming functionalities is presented. The unit cell is characterized by broadband, low profile and low loss. Due to the asymmetric structure, the proposed metasurface shows different responses to different linear-polarized incidences. For a particular linear-polarized incidence, the polarization direction of transmitted waves will be rotated by 90° in 3.72-8.28 GHz with high polarization conversion ratio (PCR). However, for the orthogonal-polarized ones, the incidence will be reflected totally and the polarization remains. The operating mechanism of proposed metasurface is analyzed both by theoretical investigations and numerical simulations. Measured results of the fabricated samples are in good agreement with the simulated ones.
