Description

technical field [0001] The invention relates to a method for researching micro-discharge of microwave components loaded with double-sided dielectric, and belongs to the field of micro-discharge of high-power microwave components. Background technique [0002] In the satellite communication system, the micro-discharge phenomenon of dielectrically loaded microwave components seriously affects the working stability of high-power loads. Space dielectric microwave components are mostly double-sided dielectric loading structures, and the electrostatic field generated by the charge accumulation on the surface of the double dielectric layer increases the complexity of the micro-discharge process. [0003] In the research field of spacecraft components, the secondary electron multiplication effect of satellite system high-power components is also called micro-discharge effect, and micro-discharge will directly affect the success or failure of satellite use. For example, the micro-di...
