摘要
基于麦克斯韦方程组,导出金属环状波导内电磁场的数学模型,在此基础上分析了环状波导内电磁场的模式特征,并以TE模式为例详细分析了其分布特性,近、远场特性。
The mathematical model of electromagnetic field in the annular waveguide with all - metallic materials is presented based on Maxwell equations. Mode properties of electromagnetic field in the annular waveguide is analyzed based on this model, and the properties of the electromagnetic field distribution, near - and far - field of TE modes are analyzed in detail.
