摘要：

Bitron, as a new type of high-power microwave device, is studied in this paper. The parameters (such as microwave power and its efficiency) based on the theoretical analysis has been realized on 2.5D Particle in Cell (PIC) simulation code. This device is composed of two parts: a modulation cavity and an output cavity. Coupling exists between these two cavities, so the oscillation occurs under certain conditions. X band bitron is designed in this paper, and its theoretical efficiency is 29.4%. The process is also realized by 2.5 PIC simulation code, with an efficiency 28%, microwave frequency 9.42 GHz, and the power output 2.25 GW.
