Wideband Airy Beam Generation Using Reflective Metasurfaces with Both Phase and Amplitude Modulation

Airy beams are an intriguing type of non-diffraction wave packet that can exist in one-dimensional (1D) curved orbital plane systems. These have gained significant attention due to their unique properties, including non-diffraction, self-healing, and self-bending. In this study, we propose a method for generating high-efficiency wideband microwave sections with reflective geometry, which is challenging achieve the complexity beam’s function generation structure. Our approach involves both phase modulation amplitude modulation. The designed metasurfaces were numerically simulated obtain most features beam. addition, they well agreement those predicted by theory.
