Abstract

All-metal RF interaction structures have potential to be used in high-power high-frequency gyro-devices. With this\nintension, the vane-loaded all-metal RF interaction structure has been field analyzed in this paper. Electromagnetic fields in\nvarious regions of the structure, boundary conditions, and finally dispersion relation for the structure have been derived\nstarting from the basic principles. Dispersion relation has been solved using Powel-Dogleg method. Validation of the present\nanalysis has been done for the special case of zero vane angle, and vane depth equal to outer radius of structure wall radius,\nwhich is identified as the dispersion relation of the 0n TE
