A three-dimensional numerical simulation method of multipactor in open-structured high-power microwave systems is presented in this work. This method considering the perfect absorption of electrons at open boundaries, the commonly used absorption method with perfect-matched layers in electro-magnetic simulations has been modified and an improved absorbing boundary has been established which avoids...
A novel method for the multipactor breakdown inhibiting of microwave components is described in this paper. It is a new surface treatment with regular porous structure on silver plated by the photolithography technique. The influences of the regular porous structure for secondary emission are studied with theoretic analysis and experimental research. The abilities to increase the multipactor power...

In this paper a numerical simulation of metal surface secondary electron emission is performed by considering scattering models. Based on the scattering models of corresponding electron energy, the characteristics involving with secondary electron emission yield dependence of the incident energy and incident angle, as well as the emitted-energy spectrum are simulated. The simulation results accord...
