A Novel Broadband Bi-Functional Metasurface for Vortex Generation and Simultaneous RCS Reduction

In this paper, a broadband bi-functional metasurface is presented with capabilities of generating vortex beam for y-polarization and reducing the backward radar cross section (RCS) for x-polarization. With careful optimization, a meta-atom is first designed to control reflection phases for orthogona...
