According to the requirement of relativistic backward wave oscillator, a mode converter (and also a reflector). It converts the operating TM11 mode to TE11mode and at the same time, reflects the TE11 wave. At last, Gaussian-like HE11 mode is output by a metal horn. It is designed as a periodic cylindrically symmetric sinusoidal corrugation waveguide. and operates in 10GHz. Numerical simulations show the conversion efficiency in center frequency is over 90 percent, and the bandwidth is about 0.3GHz.
