Abstract :
Vane loaded coaxial structures have been found useful for mode rarefaction, when used in oversized, over-moded gyrotron amplifiers. Also such circuits can compensate for the gain reduction which normally occurs while broad-banding of gyro-TWTs. This magnetron like structure was analyzed for its cut-off wave numbers by various techniques. In the present paper the dispersion and interaction impedance characteristics are obtained by boundary matching technique. The results are compared with simulated data obtained using CST microwave studio for TE01-mode.
