【摘要】 采用矢量基函数的有限元方法 ,在开放边界处采用完全匹配层 (PML)截断无限区域。分析了在圆形槽波导不同位置加载平板状介质时的模式特点。分析表明介质加载时圆形槽波导的模式次序要发生变化 ,为设计圆形槽波导微波化学反应器提供了依据。更多还原

【Abstract】 In this paper, finite element method (FEM) with vector basis function is utilize d to analyze the mode characteristics of the circular groove guide (CGG) loaded with dielectric plate in different position by setting perfectly matched layer ( PML) around the open boundary of CGG to truncate the infinite analysis domain. T he result that the presence of dielectric plate inside CGG changes the mode orde r will be useful for the design of the microwave chemical reactor based on CGG.更多还原
