摘要
用波导本征模展开方法对用于高功率微波发射系统的方角锥高斯馈源口面场进行分析 ,提出结合馈源远场辐射特性和避免高功率击穿折衷选定相应的高斯模注腰半径 ,进而确定多个波导模幅值 ,从而为运用模匹配或耦合波理论设计高斯馈源提供依据。
A High Power Microwave square pyramidal Gaussian feed aperture field is analyzed by using the waveguide intrinsic mode expansion method. The key parameter is the gaussian beam waist radius w that is determinded by compromise of the radiation charateristics and breakdown avoidance. The mode ratios of the square waveguide multimodes can be calculated with the slected w, that makes a base for designing a Gaussian feed by mode matching or coupling wave theory.
