Abstract

The invention relates to a mode exciter from a rectangular waveguide TE<10> mode to a round waveguide TE<21> mode and a design method. The work wavelength of the mode exciter is Lambda, and comprises rectangular waveguide and round waveguide; the rectangular waveguide comprises an input port and an output port; the round waveguide comprises a short circuit surface and an output port; the output port end of the rectangular waveguide is tipsily embedded into the round waveguide in a position with the distance being 1 / 4 work wavelength away from the short circuit surface, so that electromagnetic waves are transmitted to the output port of the round waveguide from the input port of the rectangular waveguide; the mode excitation on the round waveguide can be realized; the narrow edge of the rectangular waveguide is vertical to the axial line of the round waveguide; the center line of the rectangular waveguide and the axial line of the round waveguide form an included angle being theta; the length of the rectangular waveguide is 1 to 2 times of the work wavelength; and the length of the round waveguide is 5 to 7 times of the work wavelength. The mode exciter provided by the invention has the advantages that the structure is simple; and the work frequency band and the mode conversion efficiency can meet the requirement of the propagation characteristic measurement of the TE<21> mode in a gyro traveling wave tube high-frequency system.

Description

technical field [0001] The invention belongs to the technical field of high-power microwave and millimeter wave, and specifically relates to a circular waveguide TE used in the measurement of high-frequency systems of high-power millimeter-wave cyclotron traveling wave tubes. 21 mode stimulator. Background technique [0002] Rectangular waveguide TE 10 to circular waveguide TE 21 The mode exciter is a widely used microwave measurement (such as the TE in the high frequency system of the cyclotron traveling wave tube). 21 Mode propagation characteristics measurement, etc.), satellite communications, spaceborne radar, microwave power synthesis and other fields of microwave passive devices. Traditional rectangular waveguide TE 10 to circular waveguide TE 21 The mode exciter mainly adopts the structure of coaxial waveguide coupling and porous waveguide coupling. [0003] The structure of the coaxial waveguide coupling is to first connect the TE of the rectangular waveguide ...
