Abstract:

This monograph presents an experimental demonstration of two heretofore unobserved nonlinear effects in systems supporting space-charge waves. The discussion is based on a physical theory which exhibits second-order coupling of these waves to those supported by an external circuit. The physical theory, a perturbation analysis in displacement variables, describes all possible second order nonlinear interactions. The model is further specialized to the empirically valid case of a two-mode, circuit-to-stream wave interaction. An experimental coupler, designed to test these principles, is described. The low-noise amplification possibilities of devices using these principles and several problems connected with the pumping modulation are discussed. Finally, a number of alternative configurations are proposed, including a new class of fast-wave amplifiers.
