Problems solved by technology

This directly leads to the impossibility of conducting experimental research on the winding double-comb slow-wave system, and even the theoretical simulation analysis cannot be carried out in the existing particle simulation software, resulting in the stagnation of research on circularly polarized traveling wave tubes

Embodiment Construction

[0020] An energy coupling device suitable for winding double-comb slow-wave structures, such as figure 2 As shown, it includes an in-line double-comb loaded circular waveguide 4 and a double-ridge loaded rectangular waveguide 3 . The in-line double-comb-loaded circular waveguide 4 is coaxially and overlappingly connected together by a plurality of equal-diameter double-ridge-loaded circular waveguide sheets; wherein the double-ridge-loaded circular waveguide sheets 1 of even or odd positions (such as image 3 shown) the ridge heights are equal, and the remaining odd-numbered or even-numbered double ridges load the circular waveguide plate 2 (such as Figure 4 As shown), the height of the ridge increases gradually. Since the sum of the thicknesses of two adjacent circular waveguides is the comb period length p, and because the heights of the ridges loaded by two adjacent circular waveguides are not equal, all the circular waveguides The loaded double ridges form an in-line do...

Abstract

An energy coupling device suitable for a winding double comb teeth slow wave structure, belonging to the technical field of vacuum electrons, comprises an in-line double comb teeth loaded cylindrical waveguide (4) and a double-ridge loaded rectangular waveguide (3); the in-line double comb teeth loaded cylindrical waveguide (4) is composed of a plurality of double-ridge loaded cylindrical waveguide sheets having equal diameter and being coaxially superposed together; wherein the double-ridge loaded cylindrical waveguide sheets at even digit positions or odd digit positions have same ridge height, the double-ridges loaded by all the cylindrical waveguide sheets form the in-line double comb teeth structure with gradually reduced comb teeth height; and the double-ridge loaded rectangular waveguide (3) is connected with the in-line double comb teeth loaded cylindrical waveguide (4) by a round metal short-circuit board having an input-output window. The energy coupling device suitable for the winding double comb teeth slow wave structure implements that microwave signal energy can be coupled into the winding double comb teeth slow wave structure well, the amplified microwave signal energy can be perfectly extracted from the winding double comb teeth slow wave structure, and simultaneously, the energy coupling device is easy to be connected with the prior standard waveguide devices.

Description

technical field [0001] The invention belongs to the technical field of vacuum electronics, and in particular relates to an input and output structure in a circularly polarized traveling wave tube. Background technique [0002] Traveling wave tube is the most important type of microwave source in the field of vacuum electronics technology. It has the characteristics of high power, high efficiency, high gain, broadband and long life. It is widely used in radar, guidance, satellite communication, microwave remote sensing, and radiation measurement. And other fields, its performance directly determines the level of equipment. The core component of a traveling wave tube is a slow wave structure. The commonly used slow-wave structures include helix, coupled cavity, and meander waveguide. Due to the influence of space charge effect, devices composed of these slow-wave structures have strong nonlinear characteristics. [0003] In order to substantially reduce the nonlinear charac...
