The Vortex Electron and Radiated Vortex Photon of Electromagnetic Wave:Vortex Microwave Photon Radiation
The theoretical model of cyclotron electron to radiate vortex microwave photons is crucial for the technolo-gy of quantum state vortex electromagnetic wave.This paper is the second part of"The Vortex Electron and Vortex Micro-wave Photon"series,which establishes the theoretical model related to the"Vortex Microwave Photon Radiation".The ra-diation by energy level transition of electrons can generate a single microwave photon carrying IOAM(Intrinsic Orbital An-gular Momentum).Aiming to clarify this radiation mechanism,the probabilities of Landau energy level transition in non-relativistic and relativistic effects are deduced.Because of the linear relationship between the Landau energy level and the IOAM in the non-relativistic effect,the electron can only radiate the plane wave photons regardless of the initial state of the transition.It is opposed to the relativistic effect,where the microwave photon with rich IOAM modes values can be ob-tained.This paper also points out that in practical engineering,some cyclotron devices can be used as radiation sources.For mode selection,according to the characteristic of the frequency distinction between different IOAM modes,the iris-em-bedded waveguide filters can be used for frequency selection.At the same time,the microwave photons of specific IOAM modes can be selected.This paper concludes with a discussion of the quantum and statistical state vortex electromagnetic waves which reveals the corresponding pro and con in wireless communications.
