Abstract

Based on the application of millimeter wave technology has become the intelligent transportation, virtual reality, health core technology, combined with vortex wave mode reuse advantage, vortex millimeter beam become 5G era research hotspot in the field of communication and detection, but the characteristics of the vortex beam rapid divergence has become an important bottleneck restricting the development of vortex millimeter wave application technology. Drawing on the optical wavefront shaping technology, regulating the wavefront of millimeter vortex wave is a feasible way to suppress the transmission divergence effectively. In this paper, the polarization state of the Gaussian millimeter vortex wave is regulated, and then, the geometric phase generated during the polarization transformation is reconstructed to realize the arbitrary regulation of the transmission energy flow and effectively suppress the beam divergence in the transmission process. By conducting numerical experiments on different orbital angular momentum modes, the beam width by 35% at the target distance. This study provides a feasible new method for determining the optimal beam width in the communication and detection field of vortex millimeter wave.
