摘　　要：波导内电磁场结构复杂,为了解矩形波导中电磁场分布特征,由矩形波导中的TM波和TE波场方程确定波导空间任意时刻、任意位置各分量量值,进而确定空间任意位置电场和磁场矢量的指向,模拟出波导截面和纵剖面的TM11波和TE11波的电磁场分布图。模拟结果得出的结论符合实际,正确地反映了矩形波导中电磁波传播特征,对了解波导中电磁场特性具有重要意义。Waveguide electromagnetic field structures is complex, to understand the electromagnetic field distribution in a rectangular waveguide, with the TE and TM wave equations, each component of electromagnetic field can be determined at any time anywhere in a rectangular waveguide; and then determined the vectors directing of Electric and magnetic fields anywhere in waveguide, so simulated the TM11 and TE11 wave distributions for waveguide cross-section and longitudinalsection. Conclusions of the simulation results are in line with the actual, properly reflect the characteristics of electromagnetic wave propagation in a rectangular waveguide, so are of great significance for understanding its characteristics.
