Abstract
We report a theoretical study of mode coupling and power transfer in a coaxial sector taper. The power transferred from the desired TE01 mode into other propagating modes is calculated as a function of taper length and operating frequency. Power transfer via mode coupling involves at least three other modes: TE21’ TE22’ and TM21. Power transfer as a function of final sector angle is also shown. At sector angles greater than 180° the taper is highly over-moded. This type of waveguide taper is utilized to feed a wide-band input coupler for gyrotron traveling wave amplifiers.
