Abstract

Based on the theory of classical electrodynamics and quantum mechanics, we quantitatively deduce microwave carrying Orbital Angular Momentum (OAM) radiated from the moving free electron beams on different closed-curved trajectories. It shows that the non-relativistic free electrons can also transit quantized OAM to the microwave in addition to the relativistic cyclotron electrons in the magnetic field. This work indicates the effective way to construct the antennas to generate high OAM modes of the microwave by multi-electron radiation.

This work has been supported by National Natural Science Foundation of China with project number 61731011.
