A design method for the slow-wave structure of a stripped injection traveling-wave tube working in high-order modes

Abstract

The invention discloses a design method for a slow-wave structure of a strip traveling wave tube working in a high-order mode, and relates to the fields of microwave electronics and terahertz technology. The advantage of this design method is that the banded beam traveling wave tube can successfully work in high-order modes, which removes the restriction of the cut-off frequency on the width of the electron channel, fully utilizes the advantages of the banded beam beam with a large width, and greatly increases the efficiency of the banded beam traveling wave. tube power capacity. At the same time, due to the expansion of the size, the difficulty of processing and assembly is further reduced, and it is also conducive to the operation of the device under high voltage, which increases the interaction impedance, thereby realizing the improvement of the efficiency of electron injection and electromagnetic wave conversion. Compared with the traveling wave tube of the circular cross-section electron beam in the traditional working mode, the power capacity is nearly an order of magnitude higher.

Description

Technical field [0001] The present invention relates to the field of microwave electronics and terahertz technology, and more particularly to a design method of a staggered grid strip-shaped notes waveguise for high-order mode operations. Background technique [0002] It is well known that a series of superior features of Taihazbo makes it a very important academic and application value (partially in practical stages). This also enabled the world to pay great attention to the research and application of Taihaz Science and Technology, which is based on the United States, Europe and Japan. The universal consensus reached in China: It has provided an excellent opportunity for science and technology innovation, national economic development, national security construction, etc., and may trigger the revolutionary development of science and technology. [0003] The most important factor currently restricting the development of Thareez technology is the lack of terahez sources with suff...

AI Technical Summary

Problems solved by technology

However, as the frequency rises to millimeter waves, the size co-transition effect makes the electron channel width of the stripped traveling wave tube greatly reduced, thus greatly limiting the power capacity, and making the development of the stripped traveling wave tube to the millimeter wave field encounter a bottleneck.
