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 beams have gained significant attention due to their unique properties, including non-diffraction, self-healing, and self-bending. In this study, we propose a m...

| description | Airy beams are an intriguing type of non-diffraction wave packet that can exist in one-dimensional (1D) curved orbital plane systems. These beams 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 and wideband Airy beams in microwave sections with reflective geometry, which is challenging to achieve due to the complexity of the Airy beam’s function and generation structure. Our approach involves both phase modulation and amplitude modulation. The designed metasurfaces were numerically simulated to obtain the most significant features of the microwave Airy beam. In addition, they are well in agreement with those predicted by theory. |
