DESIGN OF A TM01-TE01 TRANSMISSION LINE FOR HIGH-POWER MICROWAVE APPLICATIONS
In this paper, we report the design methods and numerical results for a kind of high-power microwave (HPM) circular waveguide transmission line, which has a 90-degree bend to change the wave propagating direction for certain purposes, and meanwhile, also acts as a TM01-TE01 converter, transforming the HPM sources generating TM01 mode into the TE01 mode. A type of mode conversion sequences, i.e. TM01-TE11-TM11-TE01, is proposed. In the sequences, a 90-degree-bend circular waveguide TM11-TE01 mode converter is adopted to change the wave propagating direction. Besides, compact, linear TM01-TE11 and TE11-TM11 mode converters are designed to perform the mode conversion from TM01 mode to TM11 mode. The transmission efficiency of the designed transmission line is 97.9％ at 3.5 GHz, and the bandwidth for efficiency>90％ is 5.3％.
