摘要：
In this paper, vortex wave radiation from pseudo-traveling-wave ring resonators is demonstrated for the purpose of generation and tunable characteristics of orbital angular momentum (OAM) modes. The resonator is composed of nonreciprocal composite right/left handed transmission line on a normally magnetized ferrite ring. The numerical simulation and experimental results clearly show generation of multiple OAM modes with l = +/- 1 and +/- 2, and tunable mode selection by changing the applied dc magnetic field.
