Numerical studies of the annular waveguide laser electromagnetic field with allmetallic materials

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.福建省自然科学基金资助(项目编号:A0210007
