| Summary: | Summary: This article establishes a physical model of the interaction between surface electron beams and plasma with a transverse magnetic field. The dispersion relationship between electron beam and transverse magnetized plasma interaction was derived using perturbation method and field matching method, respectively. We studied the effects of magnetic field, plasma density, electron beam density, and electron beam velocity on radiation frequency and bandwidth. The correctness of the aforementioned results was further verified through simulation analysis. The results show that the stronger the transverse magnetic field, the higher the radiation frequency, but the smaller the radiation bandwidth; the higher the plasma density, electron beam density, or electron beam velocity, the corresponding radiation frequency and radiation bandwidth increase accordingly.
