An Angularly Stable Anisotropic Metasurface for Polarization Conversion Applications

This paper presents an anisotropic metasurface that can work as linear and circular polarizer simultaneously. The proposed design has the ability to achieve linear-to-linear polarization (LTL) within two frequency bands ranging from 7.2-10.51 GHz and 15.81-17.48 GHz. The linear-to-circular (LTC) polarization is also accomplished within the frequency ranges between 6.78-6.89 GHz, 12.54-13.76 GHz and 18.39-18.82 GHz. The proposed design provides stable response against incidence angles up to 30°. The investigated metasurface with the multi-band and multi-polarization capabilities, the compact size and the angular stability can be suitable for several applications related to satellite communications.
