    Full-space trifunctional metasurface with independent control of amplitude and phase for circularly polarized waves by Li Xi Ming, Zhao Yuan, Lu Ren Pan, Sun Xiao Feng, Yang Zhao, He Hai Dan, Liu Yan Hui, Du Guo Hong

    Published 2024-10-01
    “…Herein, an innovative strategy of trifunctional metasurface is proposed to independently and simultaneously manipulate the amplitude and phase of circular polarized waves in full space. The multifunctional design is composed of double-layer anisotropic metasurface sandwiched with a bandpass frequency selective surface, with a frequency-direction multiplexed paradigm for on-demand control of both amplitude and phase across three independent channels. …”

    Wind Field Retrieval From Co-Polarized SAR Imagery Without External Wind Direction Assistance by Xianen Wei, Jinsong Chong, Yawei Zhao, Lijie Diao, Xuan Jin

    Published 2025-01-01
    “…Obtaining wind direction relies directly or indirectly on external sources, making it impossible to achieve wind field retrieval solely based on co-polarized SAR images. This study takes advantage of the fact wind direction is similar to wind waves propagation direction, relying solely on co-polarized SAR images to obtain proper wind direction, thus enabling wind field retrieval without external wind direction assistance. …”
