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.
