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 ...
i.e., the mode with the lowest cutoff frequency.Note:Designations for the dominant mode are TE10for rectangular waveguides and TE11for circular waveguides.See alsocutoff frequency,fiber optic waveguide,lowest

a metal rod between the circular waveguide and the rectangular waveguide passes through a common wall thereof and strides into the two waveguides, a metal block is arranged in the rectangular waveguide, the metal block is provided with a through hole, and a metal round rod is positioned in the...
The radiation characteristic of the dominant beam mode of a lens-type beam waveguide is discussed; the assumption is made that this mode illuminates a circular aperture in a metallic screen. Radiation patterns are presented for various aperture radii and various distances between the aperture plane ...
