一种基于过模波导的高功率8 mm微波传输系统
Design of a high-power 8 mm microwave transmission system based on over-moded waveguide
摘要
Abstract
An over-moded waveguide is a kind of waveguide structure which breaks through the power capacity limitation of a traditional single mode waveguide. Mode transitions and mode filters based on over-moded waveguide are key components in a high power microwave system. The design theory of these components is discussed, and a set of 8 mm high-power over-moded microwave power transmission system is designed,including over-moded waveguides, a mode transition, and a mode filter. The mode filter can remove high order modes by sheet and slots. Modeling and simulation are performed by using CST Microwave Studio. The simulation results show that the over-moded transmission system suppresses the resonance of high order modes efficiently and therefore enhances the microwave power transmission efficiency.关键词
