【摘要】 本文利用本征函数展开法推导了色散方程,进一步得到耦合阻抗和欧姆损耗等高频特性。通过数值计算以及软件仿真相结合的方法相互验证计算结果的准确性,具体分析了两种矩形单栅慢波结构:以高阶模式作为工作模式的较大尺寸慢波结构和以基模为工作模式的较小尺寸慢波结构。通过比较两种结构的高频特性,分析了以高阶模式作为工作模式的可行性。更多还原

【Abstract】 For the rectangular waveguide grating slow-wave structure, the dispersion relation was obtained by the eigen-function method. The coupling impedance and the Ohmic loss were derived from the relevant equations. Two theoretical models were studied by comparing their calculation results of the HF characteristics of the rectangular waveguide grating slow wave structure with those obtained by HFSS code and CST-MWS. The HF characteristics of the largersize SWS operating in the high order mode and the SWS operating in the fundamental mode were compared, and the results presented in this paper demonstrate the possibility of using the high-order mode in devices.更多还原
