Abstract

A method for the improvement multipactor discharge of microwave components is described in this paper. It is a kind of surface treatments with regular micor-porous structure by the photolithography technique or irregular micro-porous structure by chemical etching process on silver plated coatings. Their influences of the micro-porous structure for secondary emission are compared. A C-band impedance transformer is used to valid multipactor discharge level by three-dimensional simulations and experimental results. Results show that this method can improve greatly the multipactor discharge of microwave components in theory and experiments.
