Bitron - a new high power microwave device

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