Abstract: We demonstrate a metasurface-based ultrathin flat lens operating at microwave frequencies. A series of subwavelength metallic split-ring resonators, which are sandwiched between two cross-polarized metallic gratings, are defined to obtain a radially symmetric parabolic phase… read more here.

Abstract: An all-dielectric double-layer grid grating is proposed and demonstrated theoretically and experimentally to realize the angular filtering effect. The theoretical results show that the transmission of the double-layer grid grating drops sensitively, as the incident… read more here.
