Problems solved by technology

However, the electric field strength of this slow-wave structure in the direction of electromagnetic wave transmission is relatively weak, so its coupling impedance is small, which leads to the application of traveling wave tubes with low output power, low interaction efficiency, and low gain. and long saturated interaction lengths

Embodiment

[0027] Such as image 3 and Figure 4 As shown, the dome-trapezoid interleaved double-grid slow-wave structure provided in Embodiment 1 includes an upper grid part and a lower grid part respectively arranged on the upper and lower sides, and the upper grid part and the lower grid part are both arranged There are ups and downs 1 that extend in the lateral direction and periodically fluctuate up and down along the lateral direction. The ups and downs 1 on the upper and lower sides are staggered by half the ups and downs period, and the width of the ups and downs 1 on both sides is a, while the up and down sides The distance between the corresponding positions of the part 1 is b, the lowest end of the upper side undulating part 1 is higher than the highest end of the lower side undulating part 1, and the height difference is hb, so that a structure with a height of hb and a width of a is formed between the two. The strip-shaped electron injection channel 5, the undulating part 1...

Abstract

The invention discloses a dome trapezoidal staggered double-gate slow wave structure, and belongs to the technical field of electric vacuum devices. The structure comprises two fluctuating parts whichare respectively arranged at the upper side and the lower side. Each fluctuating part is mainly composed of a plurality of trapezoidal parts, a circular groove part and a circular top part, wherein the plurality of trapezoidal parts are sequentially arranged at intervals in the transverse direction; the adjacent trapezoidal parts are in transition through the circular groove part; in the longitudinal section parallel to the transverse direction, the trapezoidal parts are isosceles trapezoids with the heights extending in the longitudinal direction, and the upper bottoms of the isosceles trapezoids at the upper side and the lower side are arranged on the sides, close to a strip-shaped electron beam channel, of the isosceles trapezoids, round top parts are connected to the upper bottoms ofthe isosceles trapezoids, and the lower bottoms of every two adjacent trapezoid parts in the transverse direction are in transition through a round groove part between the two trapezoid parts. According to the structure provided by the invention, the dispersion curve is more flat while the coupling impedance is increased, so that the defects of the existing sine wave guide slow wave structure areeffectively overcome.

Description

technical field [0001] The invention relates to the technical field of electric vacuum devices, in particular to a dome-trapezoid interlaced double-grid slow-wave structure. Background technique [0002] An electric vacuum device is a device that converts the kinetic energy of electrons into electromagnetic wave energy. The slow wave structure is its main transducing structure. In the slow wave structure, the electron beam interacts with the electromagnetic wave to amplify the electromagnetic wave signal. [0003] There are many kinds of slow-wave structures, such as folded waveguide structure, sinusoidal waveguide structure, rectangular interleaved double-grid structure, etc. Among these slow-wave structures, the working bandwidth of the folded waveguide slow-wave structure is relatively wide, but its electron injection The processing of the channel is difficult, the transmission loss in the terahertz frequency band is large, and the processing is relatively difficult; the...
