Abstract

A plasma-filled diode can be taken as a simplified model for the interaction space of some microwave oscillators, such as, virtual cathode oscillators. A magnetic field has played an important role in showing the nonlinear dynamics of the diode in a previous study. In the presence of a magnetic field, the diode is connected to various types of loads consisting of capacitance, inductance, and resistance in series. The nonlinear dynamics and chaos have been investigated by using both analytical analysis and particle-in-cell simulation. It has been shown that the diode can operate in different dynamical regimes: steady, oscillatory, chaotic, and unstable.
