Abstract: This letter presents a novel dual-focusing phase synthesis method aimed at achieving high-gain beam control using caustic Bessel-like beams. Compared to conventional geometric optics methods ...

Abstract: In this article, a phase-only beam forming method based on digital code metasurface (DCM) is proposed for sidelobe level suppression. First, a joint magnitude-and-phase equivalent model is ...
