影响星载微波部件微放电阈值的Furman模型研究

星载微波部件的微放电效应是影响航天器微波传输系统独特的瓶颈问题之一。以星载微波部件微放电阈值仿真中广泛使用的Furman模型为研究对象，以平行平板传输线为例，研究并获得了Furman模型中本征二次电子、弹性散射电子、非弹性散射电子3类电子的模型参量对微放电阈值的影响规律，并通过对总二次电子发射系数的影响合理解释了微放电阈值的变化规律，为星载微波部件微放电阈值的精确仿真提供了规律指导。

Influence of the Furman model on the multipactor threshold of satellite-borne microwave component

The multipactor effect of satellite-borne microwave components is one of the unique bottleneck problems affecting the microwave transmission system of spacecraft. Aiming at the Furman model which is widely used in the multipactor analysis and simulation, the influence of the model parameters of three types of electrons, including the true secondary electron, the backscattered electron, and the rediffused electron, on the multipactor threshold are studied with the parallel plate as an example. While the variation trends of multipactor threshold with parameter are also explained reasonably. The paper provides guidance for the accurate simulation of multipactor threshold of satellite-borne microwave component.
