Embodiment Construction

[0013] In the following, the present invention will be further described in detail in conjunction with the design example of the high-frequency interaction system of the W-band confocal waveguide gyrotraveling wave tube and the accompanying drawings:

[0014] When the electromagnetic wave is transmitted in the confocal waveguide, it will also propagate along the longitudinal direction while radiating outward along the transverse direction, so the radiation field will form an included angle with the central axis of the waveguide, and the microwave will also propagate along the longitudinal direction. diffraction.

[0015] Therefore, a periodic distribution eccentric dielectric ceramic ring absorber separated by copper plates is designed to block the diffracted electromagnetic waves and prevent the energy crosstalk of diffracted microwaves.

[0016] figure 1 It is a three-dimensional structural diagram of a microwave absorbing device with a periodically distributed confocal wa...

Abstract

The invention discloses a periodically distributed confocal waveguide dielectric ceramic ring microwave absorption device, which relates to the technical fields of microwave, millimeter wave and terahertz devices. In the present invention, the dielectric ceramic ring and the copper plate are periodically distributed along the longitudinal direction, and the copper plate is in close contact with the dielectric ceramic ring, while maintaining a certain gap with the mirror surface of the confocal waveguide to avoid its influence on the microwave transmitted by the confocal waveguide. The copper plate used in the present invention can cut off the diffracted microwaves, and the diffracted microwaves will only be reflected and absorbed multiple times in the respective dielectric ceramic ring absorption units, effectively preventing energy crosstalk between different dielectric ceramic ring units, while avoiding The impure output mode and terminal reflection caused by the incompletely absorbed parasitic mode reflection entering the high-frequency structure interaction system and the output end of the high-frequency structure improve the working stability of the confocal waveguide gyrotraveling wave tube.
