Abstract

The invention discloses a twisted waveguide separating type directing plane ridge waveguide folded waveguide. The twisted waveguide separating type directing plane ridge waveguide folded waveguide comprises at least two shortest waveguide period structures which are sequentially communicated in the Z-axis direction and an input and output waveguide; the twisted waveguide separating type directing plane ridge waveguide folded waveguide is composed of a plurality of U-shaped bent waveguides, twisted waveguides and straight waveguides. When the twisted waveguide separating type directing plane ridge waveguide folded waveguide is applied to a traveling-wave tube contour line electromagnetic wave vacuum device, compared with a traditional folded waveguide, the twisted waveguide separating type directing plane ridge waveguide folded waveguide has the advantages that the 180-degree phase difference brought by the U-shaped bent waveguides existing when an electron beam passes through a traditional slow-wave structure is overcome, and the working bandwidth of an electromagnetic wave source can be better widened. Through the directing plane structure, all electromagnetic wave structures can be arranged on a base, and work is completed at a time through a common numerical control milling machine, so that the machining precision is guaranteed, and the machining cost is reduced. The twisted waveguide separating type directing plane ridge waveguide folded waveguide can achieve compact delay lines of various waveguides or single-ridge waveguides or double-ridge waveguides, and especially the slow-wave structure of a compact traveling-wave tube amplifier and the like.

Description

technical field [0001] The invention relates to an electromagnetic wave transmission line. Specifically, it relates to a compact twisted waveguide split quasi-planar ridge waveguide folded waveguide for signal delay or slow wave structure of electromagnetic wave source. Background technique [0002] The first important application of folded transmission lines was as a signal delay line, used for signal delay in systems such as radar. A second important application of folded transmission lines is as a slow wave structure in traveling wave tube amplifiers. At this time, the electron beam propagates along a certain straight electron channel, while the electromagnetic wave propagates along the bent transmission line. Although the phase velocity of the electromagnetic wave propagating in the bent transmission line is very fast, which can be close to the speed of light, or even greater than the speed of light, but in the straight electron channel, the phase velocity of the elect...
