Embodiment

[0022] figure 1 It is a structural diagram of a metal slow-wave device with different planes interlaced relative to each other in the present invention.

[0023] In this example, if figure 1 As shown, the present invention is a metal slow-wave device with different planes interlaced relatively, including: two sets of metal sheets and metal shells placed on different planes and interlaced with each other;

[0024] The two groups of metal sheets 1 and 2 are identical in shape, including two curved sections 5 and 6 and a straight line connecting the two curved sections, and the width and thickness of the curved section and the straight section are equal;

[0025] Such as figure 1 As shown, the curve segment includes a quarter arc segment and two short straight line segments connecting the arc segment, wherein the two endpoints of the arc segment are respectively connected to one of the end points of the two short straight line segments, and the arc segment Tangent to both shor...

Abstract

The invention discloses a metal slow wave device relatively interlaced in different planes. The metal slow wave device having interlaced metal sheets is formed by replacing an existing zigzag metal strip with two groups of metal sheets which are relatively interlaced in different planes. In this way, electromagnetic waves are transmitted by means of the electromagnetic field coupling between the interlaced metal sheets. When passing through the metal slow wave device, an electron beam interacts with an electromagnetic wave signal on the metal slow wave device so as to exchange energy with thehigh-frequency signal. Compared with existing planar slow wave structures, the metal slow wave device has high amplification efficiency, low coupling impedance, weak chromatic dispersion, and a flat dispersion curve.

Description

technical field [0001] The invention belongs to the technical field of microwave electric vacuum devices, and more specifically relates to a metal slow-wave device in which different planes are relatively interlaced. Background technique [0002] Vacuum electronic devices are systems that use charged particles (usually electrons) to interact with electromagnetic waves in a vacuum, and convert the DC energy of the electron beam into electromagnetic wave energy output. It has high output power, wide frequency bandwidth, high efficiency, and anti-interference Among them, the planar slow wave structure has the advantages of small size, integration, and low operating voltage. [0003] Since the planar slow-wave structure is a 2-D structure, it can be mass-produced by means of micro-fabrication, which solves the difficult problem of traditional slow-wave structure processing above the millimeter wave band. A typical representative of the planar slow wave structure is the microstr...
