A Cerenkov Radiation for the Production of Millimeter and Submillimeter Waves,
Abstract
A method is presented by which millimeter and submillimeter power can be generated and radiated into free space at the watt level. The method uses a combination of electronic and physical optic techniques. The electronic technique involved is the generation of Cerenkov power by passing a bunched megavolt electron beam through a non-resonant isotropi dielectric medium. The optical techniques are used to shape the dielectric to form the desired radiation pattern. One dielectric shape is analyzed that has produced 0.6 watts of power at a wavelength of 8 millimeters in a fairly sharp pattern. The pattern width was about 6 degrees and the pattern was accurately predicted by the theory. With the same cone, the pattern width becomes sharper at higher frequencies and the power level can be made to stay at about the same level or higher by using a K-band Rebatron instead of the S-band one now being used.
