Manipulating light at distance by a metasurface using momentum transformation
, 2014 A momentum conservation approach is introduced to manipulate light at distance using metasurfaces. Given a specified field existing on one side of the metasurface and specified desired field transmitted from the opposite side, a general momentum boundary

Coherent optical control of polarization with a critical metasurface
, 2015 We describe the mechanism by which a metamaterial surface can act as an ideal phase-controlled rotatable linear polarizer. With equal-power linearly polarized beams incident on each side of the surface, varying the relative phase rotates the polarization

Low-Profile Broadband Metasurface Antenna Under Multimode Resonance
IEEE Antennas and Wireless Propagation Letters, 2021 A broadband metasurface antenna is proposed in this letter. The antenna is based on a nonperiodic metasurface. The modal behavior of the metasurface and the slot is analyzed using characteristic modes analysis (CMA).

Wideband Active Region Metasurface Antennas [PDF]
IEEE Transactions on Antennas and Propagation, 2020 Modulated metasurface (MTS) antennas with broadside beam rely on the interaction between a radially modulated equivalent impedance and a surface wave (SW) with cylindrical wavefront, launched by a point source. At the frequency where the SW wavelength matches the period of the impedance modulation, the −1 indexed (leaky) mode of the Floquet-mode ...

Wideband Polarization Independent Resonant Cavity Antenna for 6G Applications
IEEE Access, 2023 In this paper, a planar polarization independent resonant cavity antenna (RCA) is proposed to achieve higher gain with a single patch connection instead of using antenna arrays with additional feeding losses.

Experimental Synthetic Aperture Radar with Dynamic Metasurfaces
, 2017 We investigate the use of a dynamic metasurface as the transmitting antenna for a synthetic aperture radar (SAR) imaging system. The dynamic metasurface consists of a one-dimensional microstrip waveguide with complementary electric resonator (cELC ...
