摘要：
In this paper, vortex electromagnetic wave with multiple Orbital Angular Momentum (OAM) beams is designed based on the pattern product method, and demonstrated by using a 1-bit coding electromagnetic surface at 12.5 GHz. First, compensated phase distributions of the electromagnetic surface are derived to realize an OAM beam and multiple pencil beams, respectively. Next, using the pattern product method, a new phase distribution is obtained to realize the multiple OAM beams. Thereafter, numerical calculation results and full wave simulation results based on a 1-bit square-patch surface are presented, which verify the feasibility of the proposed method. It provides useful reference for the subsequent realization of multiple OAM beams with adjustable function in 3D space.
