Path Loss of OAM Wave in Indoor Office Scenario at Millimeter-wave Band

Abstract

In this paper, an oribital angular momentum (wave channel measurement is conducted in an indoor scenario, three cases are designed to investigate the pa of the vortex wave. The results indicate that floating in (FI) model can fit better than close-in (CI) model for me path loss. In addition, the divergence angle of vortex wave to less received power in the line-of-sight (LOS) environn
