The invention discloses a high-power over-mode coaxial turning waveguide which mainly solves the problems that a high-power over-mode coaxial turning waveguide which is simple in structure and higher in applicability does not exist in the prior art, and a technological development requirement cannot be met. The high-power over-mode coaxial turning waveguide comprises over-mode coaxial waveguides, two 180-degree input sectorial waveguides, two 180-degree sectorial turning waveguides and two 180-degree output sectorial waveguides which are connected sequentially, wherein the two 180-degree input sectorial waveguides are connected with the two 180-degree sectorial turning waveguides respectively; and the two 180-degree sectorial turning waveguides are connected with the two 180-degree output sectorial waveguides respectively. With the adoption of the scheme, the high-power over-mode coaxial turning waveguide achieves purposes of small reflection, low loss, high power capacity and high-power application, and has very high practical value and popularization value.
Description
technical field [0001] The invention relates to a waveguide in the technical field of high-power microwaves, in particular to a high-power over-mode coaxial bend waveguide. Background technique [0002] With the development of high-power microwave technology, people pay more and more attention to high-power microwave feeder technology. Overmodulated coaxial waveguides are common components in high-power microwave systems. The output ports of many high-power microwave sources and the input ports of high-power antennas use overmodulated coaxial waveguides, and the modes are rotationally symmetrical TEM modes. In order to enable the TEM mode of the overmode coaxial waveguide to bend and transmit along the axial direction, it is of practical significance to design an overmode coaxial bend waveguide suitable for high power conditions. For the bending waveguide used in the high-power microwave field, in addition to the research on the technical properties such as low loss, low re...
