Abstract

The Orotron is a device which is capable of producing moderate (few watts) to high power levels (few kilowatts) of millimeter and sub-millimeter wavelength radiation in the frequency range from GHz to Terahertz. It consists of an open resonator containing rectangular metal grating periodic RF structure and a sheet electron beam. In this paper, 100 GHz RF interaction structure for Orotron has been designed using CST-MWS which is a 3-D e.m. field simulator. The dispersion characteristics of the RF structure are being analyzed which give the information about axial propagation constant (beta) which in turn yield the phase velocity at a particular frequency.
