作者李绍和,李九生（2019）在《Pancharatnam–Berry metasurface for terahertz wave radar cross section reduction》一文中研究指出：The digital coding metasurfaces need several kinds of meta-particle structures to obtain corresponding electromagnetic wave responses and require time-consuming optimization.In this paper, we present train-symbol-shaped meta-particles with various orientations utilizing Pancharatnam–Berry(PB) phase to achieve 1-, 2-, and 3-bit digital coding metasurfaces.Terahertz wave scattering patterns of the coding metasurfaces with regular and random sequences are given and discussed.They have strongly suppressed backward scattering with approximately-13.5 dB radar cross section(RCS) reduction in a wide band range from 0.85 THz to 1.6 THz.The proposed digital coding metasurfaces provide a simple way and new opportunities for manipulating terahertz wave scattering with polarization independence.
Abstract
The digital coding metasurfaces need several kinds of meta-particle structures to obtain corresponding electromagnetic wave responses and require time-consuming optimization.In this paper, we present train-symbol-shaped meta-particles with various orientations utilizing Pancharatnam–Berry(PB) phase to achieve 1-, 2-, and 3-bit digital coding metasurfaces.Terahertz wave scattering patterns of the coding metasurfaces with regular and random sequences are given and discussed.They have strongly suppressed backward scattering with approximately-13.5 dB radar cross section(RCS) reduction in a wide band range from 0.85 THz to 1.6 THz.The proposed digital coding metasurfaces provide a simple way and new opportunities for manipulating terahertz wave scattering with polarization independence.
