The dominant mode waveguide propagation is the most used one in the electromagnetic wave mode. In order to further understand its spread characteristics, starting from the waveguide cutoff wavelength, the conditions of single-mode transmission of electromagnetic waves were discussed, the conclusion： TE10 propagation needs that the electromagnetic wavelength and the waveguide dimensions meet certain relations. Then the electromagnetic waves equations of the dominant mode were derived; by using the equations, the distribution map for a certain frequency electromagnetic wave TE10 was simulated in a certain size rectangular waveguide; and then the main features of TE10 wave propagation were summarized. These features include that of the cutoff frequency, the selection of waveguide sizes, the impedance characteristic, the phase velocity and wavelength of a waveguide, and the transmission power of TE10 wave. Grasping these characteristics can make TE10 propagation playing a more effective role in its practical applications.
