Abstract Multifunctional metasurfaces working in the transmission‐reflection (TR) state have attracted more attention because TR metasurface integrating functionalities saves occupied space and further expands control abilities of electromagnetic waves full space. Herein, a switchable coding is proposed that can not only dynamically regulate states x / y polarizations but also realize independent phase transmitted reflected polarizations. Subsequently, based on different control, as first...
Based on a space–time-coding (STC) transmissive metasurface (TMS), we present the utilization of electromagnetic harmonic spectra in phaseless near-field microwave computational imaging (CI). Each element TMS integrates one PIN diode as switch to independently regulate transmission amplitude, giving rise 14-dB modulation depth at 21 GHz. Using and two standard horn antennas, CI system is established single-pixel manner. A simple effective scheme detailed covert monochromatic signal into...
In this paper, we present and design a tensor holographic metasurface (THMS) capable of radiating multiple beams with different polarizations in both forward backward directions. The proposed THMS manipulates the fundamental TE mode surface waves (SWs) to produce bidirectional leaky-wave radiation using bilayer anisotropic metal patches. To achieve independent control direction polarization beams, nature capacitive impedance element supporting SWs is exploited. A dual-feed scheme exciting...
