A novel approach for the theory of electron beam-wave interactions in a magnetized plasma waveguide

Based on the theory of wave propagation along a waveguide filled with moving media, such as magnetized plasma and electron beam in a magnetic field, and making use of the transformations of electromagnetic field and wave vector in Minkovsky space, a rigorous theory of electron beam-wave interactions in a magnetized plasma waveguide is presented in the paper. It is very interesting to point out that some important new physics have been revealed by the theory given in the paper.
