虚阴极的单电荷层模型
-
摘要: 通过引入虚阴极振荡的单电荷层模型，得到了虚阴极振荡产生微波的线性色散关系。同时，分析了入射、反射、透射束流中振荡成份与虚阴极振荡的两本征模式相互作用，得到非线性色散关系，并给出了虚阴极振荡产生微波的机制。Abstract: A linear dispersion relation of the Virtual Cathode Oscillator (VCO) is obtained using the single charge sheet model.Considering the interaction of the injected beam,reflected beam, and transmitted beam with VCO,the nonlinear dispersion relation is psented.Then,the reason of the wide band of VCO is analysed,and the mechanics of VCO is given from the nonlinear dispersion relation.
