Abstract

The invention belongs to the technical field of microwave engineering and specifically relates to a circular waveguide wave-mode suppressor capable of suppressing a TE11-mode microwave and a design method thereof. The circular waveguide wave-mode suppressor comprises a circular waveguide. The circular waveguide is provided with a first cavity, a second cavity, a third cavity, a fourth cavity and afifth cavity in sequence in the microwave transmission direction. A first transition waveguide is arranged between the first cavity and the second cavity; a second transition waveguide is arranged between the second cavity and the third cavity; a third transition waveguide is arranged between the third cavity and the fourth cavity; and a fourth transition waveguide is arranged between the fourthcavity and the fifth cavity. The circular waveguide wave-mode suppressor can effectively filter the TE11-mode microwave, so that a TM01-mode microwave is allowed to be transmitted more efficiently; and verification is realized based on a numerical simulation program, such as CST-MWS and HFSS software, and simulation results show the suppressor can be used in various wave bands.

Description

technical field

[0001] The invention belongs to the technical field of microwave engineering, and in particular relates to a method for suppressing TE 11 Circular waveguide suppressor for mode microwave and its design method. Background technique

[0002] In the research work of microwave engineering technology, the function of the wave suppressor is to suppress or filter out the spurious modes or other undesired modes that may exist in the microwave transmission system. These modes can be generated by the microwave source or by the mode transformer or waveguide inhomogeneities.

[0003] In microwave engineering, there are the following types of wave suppressors: coaxial conductive ring filter, radial conductive diaphragm filter, waveguide slot filter, attenuation coating filter. Their functions are to filter out the modes that affect the normal operation of the system during the transmission process of the waveguide.

[0004] Coaxial Conductive Ring Suppressor. Set a se...
