Description
A miter-bend type mode converter which has an angle-adjustable mirror is proposed to control the transmission mode content in the EC H&CD transmission line. This component excites the higher order mode by injecting a tilted RF beam into a waveguide using the angle-adjustable mirror. A mock-up model of the converter was developed to evaluate the principle of the mode conversion. The experimental result of the mock-up representing the ratio of LP01 mode and LP11 mode was successfully controlled by 10% as the theoretical prediction.
