TM01-TE11 mode converter of twisted rectangular waveguide

The invention discloses a TM01-TE11 mode converter of a twisted rectangular waveguide, and the TM01-TE11 structure of an input section is a circle formed by four arc-shaped surfaces, and the four arc-shaped surfaces are connected with an arc-to-rectangular waveguide transition section; two adjacent output ports of the arc-to-rectangle transition section are connected with the rectangular waveguide, the other two adjacent output ports of the arc-to-rectangle transition section are connected with the 180-degree torsion rectangular waveguide section, and the rectangular waveguide and four output ports of the 180-degree torsion rectangular waveguide section are respectively connected with four input ports of the bent waveguide section; the four output ports of the bent waveguide section are opposite in pairs, the four output ports of the bent waveguide section are extended to intersect, and the synthesis output section is connected at the intersection for output. According to the invention, the mode purity is hig
