Abstract

The invention relates to a slow wave structure of a terahertz micro-electrical vacuum folding waveguide traveling-wave tube amplifier. The slow wave structure comprises n sections of folding waveguide slow wave structures connected in sequence, wherein n is a positive integer and n is greater than or equal to 2; the first section of folding waveguide slow wave structure and the (i+1)-th section of folding waveguide slow wave structure meet that gi is smaller than g(i+1), v(i+1)/vi is equal to gi/g(i+1), gi is a folding degree of the i-th section of folding waveguide slow wave structure, vi is an electron velocity at the electron beam input port of the i-th section of folding waveguide slow wave structure, and i belongs to the range of 1 to n-1. According to the slow wave structure of the terahertz folding waveguide traveling-wave tube amplifier provided by the invention, the multi-section type folding waveguide slow wave structure is adopted, so that the power and efficiency of the terahertz micro-electrical vacuum folding waveguide traveling-wave tube amplifier are improved.

Description

technical field [0001] The invention relates to the field of terahertz vacuum electronic devices, in particular to a slow wave structure of a terahertz microelectric vacuum folded waveguide traveling wave tube amplifier. Background technique [0002] Terahertz (THz) waves are between the relatively mature microwave and millimeter waves and infrared and visible light, and are in the transition zone from macroscopic theory to microscopic quantum theory. The THz spectrum of many substances contains rich information. The unique characteristics and status of terahertz waves make them have very important application value in many fields such as basic science, material research, biomedicine, military and national public security. The lack of stable and coherent terahertz radiation sources seriously restricts the research, application and development of terahertz. [0003] For high power requirements, vacuum electronic devices are the first choice for high-power terahertz radiation...
