Primary Study On High Frequency Structure Of 38ghz Extended Interaction Oscillator

In this article, a cavity with a frequency of 38GHz is designed. Through numerical calculation and computer simulation, TM31 mode, the dispersion curve, quality factor and S-11 parameter of a high frequency structure of 38GHz extended interaction oscillator are studied. S-11 parameter is calculated to find optimum output window size for cold-test experiment. And the results of particle simulation is also shown in this article. Compared with the results of cold cavity, the results of particle simulation are consistent. This research is of great significance for the development of millimeter wave vacuum devices.
