Abstract
This letter proposes a new method for controlling the divergence angles of multimode orbital angular momentum (OAM) vortex beams. A geometric framework is established that allows for the same divergence angle across different OAM modes, which addresses a significant challenge in multimode systems. Proposed method combines 1-D linear array theory and the design of OAM beams with an equal divergence angle. By adjusting element phases, precise divergence control is achieved without altering the metasurface structure. The method's effectiveness is verified through theoretical synthesis, full-wave simulations, and experimental validation. This approach offers accurate control over a wide range of angles, demonstrating potential applications in communication systems.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
