An All-Dielectric Polarization-Selective Transmissive Focusing Metasurface

An all-dielectric polarization-selective transmissive focusing phase-gradient metasurface working at 14 GHz is proposed. The PGMS is consisted of all-dielectric cross-shaped unit cells, which are polarization-selective and present different transmission properties for the orthogonal linearly polarized plane waves. After properly setting the parameters of the unit cells, the metasurface can block the y-polarized field while transmit and focus the x-polarized field.
