摘要
以电磁场理论为出发点 ,对满足环状截面同轴金属波导边界条件的麦克斯韦方程组求解 ,得到了环状同轴波导管内的电磁场各分量方程 ,并以TE模为例详尽分析了环状金属波导管中的模式特征、色散关系。
Equations of the electromagnetic field components of coaxial waveguide with annular cross section and metallic walls are presented on the basis of electromagnetic theory. The waveguide modes are the solutions to Maxwell′s equations that satisfy certain boundary conditions at the surfaces of the inner and out metallic guide walls. Field properties, dispersion, beam propagation and intensity distribution of TE modes are analyzed in detail.
