Cross-polarization converter and wavefront modulation integrated metasurface

Abstract

A novel cross-polarized converter that receives line-polarized waves and converts them into cross-polarized ones is proposed with a 10 dB impedance bandwidth of 6.8%, based on which a 2-bit metasurface cell is constructed, which consists of only one dielectric substrate and has a cell size of only 0.14 times the electrical wavelength. The metasurface designed based on this unit can effectively beam the electromagnetic waves emitted by the horn feeder and increase the gain, which has the potential to be used in various wireless systems.
