Based on the theory of mode coupling, the geometrical structure of the TE0 1 -TM1 1 mode converter is optimized and analyzed by the traditional waveguide axis bending and the improved sinusoidal bending of the waveguide axis, and the optimal geometric parameters are obtained. The sinusoidal bending design of the 8mm high power circular waveguide TE0 1 -TM1 1 mode converter achieves a 99% conversion efficiency and a bandwidth of over 32%. At the same time, the serpentine wire circular waveguide TE0 1 -TE1 1 mode converter
