摘要

This article establishes a physical model of the interaction between relativistic electron beams and longitudinally magnetized plasma. The dispersion relationship of microwave radiation generated by longitudinally magnetized plasma excited by an electron beam was derived using the field matching method. Studied the effects of magnetic field, plasma density, and electron beam velocity on radiation frequency and bandwidth. The results indicate that as the longitudinal magnetic field or electron beam velocity increases, the plasma radiation frequency also increases accordingly; As the plasma density increases, its radiation bandwidth correspondingly increases.
