Advances in Modeling and Simulation of Microwave Tube

It is very difficult to promote performance of microwave tubes in power, bandwidth, gain, efficiency, and nonlinearity comprehensively by traditional design method based on experience. The technique of modeling and simulation is the key method to improve the capability of microwave tubes. Recent advances in modeling and simulation of microwave tube are reviewed. The classification and representative codes of microwave tubes are introduced. 2D TWTCAD and 3D MTSS (Microwave Tube Simulator Suite) developed by University of Electronic Science and Technology of China are demonstrated. Finally, some proposals how to promote Chinese's capability in developing codes of microwave tubes are given.
