Abstract:High‐speed wide‐angle radio detection is crucial for intelligent wireless systems, autonomous vehicles, rescue operations in urgent situations, and security in various fields. This can be achieved through diverse controls of electromagnetic waves. Currently, multidimensional manipulations of electromagnetic waves are determined by dynamic antennas like phased arrays, mechanical beam‐steering radars, and programmable metasurface imagers. However, these methods face challenges in achieving rapid responses and la… Show more
