Research of energy storage and discharge based on cylindrical resonator*

Abstract

This dissertation mainly studies the energy storage and release of the cylindrical resonator, and the mode converter from the TE10 mode of the rectangular waveguide to the $\mathbf{TM}_{01}$ mode of the circular waveguide is used, and the good matching of the cylindrical resonator at the resonance point of 2.9004 GHz is realized by CST software simulation optimization. The model works on TM0,1,12 modes at this frequency and forms a strong resonance. Assuming that when the energy storage is saturated, and ignoring switching and other losses, calculated that the output gain of the model increases with the increase of the pulse width by using the equivalent circuit theory. When the input pulse width is $15\mu\mathrm{s}$, the output power can achieve about 21 times gain.
