BASIC RESEARCH IN MICROWAVE DEVICES AND QUANTUM ELECTRONICS.
Abstract
A preliminary survey of the physical principles and phenomena that would most likely lead to the development of new ideas for the generation and amplification of coherent electromagnetic energy in the millimeter and submillimeter wavelength region is given. The analysis of the feasibility of frequency multiplication by means of passing a fast cyclotron wave into a magnetron-type cavity is given in some detail. Equations for the harmonic power output at the magnetron-type cavity in terms of some operating parameters are given. Experimental work on extending the technique for brazing beryllium oxide to helices designed to work at frequencies of 30 Gc and higher is reported here. Some minor difficulties experienced in obtaining good thermal contact between the wire helix and the oxide and their probable remedies are discussed. A nonlinear analysis of simultaneous amplification of two input frequencies by a traveling-wave amplifier is given here in detail. Very complex equations for the interaction process are obtained due to the nonlinear nature of the interaction which gives rise to a cross modulation of the two input frequencies. Several approximations are introduced in order to simplify the analysis. (Author)
