Nonlinear transmission lines for high power RF generation and pulse sharpening

Summary form only given.Nonlinear transmission lines have been demonstrated to be an effective technique for generating high power ultrawideband or mesoband radiation without the need for a vacuum system, electron beam, or magnet. Preliminary experiments have been performed at AFRL and UM on a discrete element nonlinear transmission line with nonlinear capacitance. Depending on the injected pulse, either pulse sharpening or RF generation could be observed. Time frequency analysis has been applied to analyze the generated RF spectrum. These effects were reproduced in circuit simulations. Results from these preliminary experiments and plans for future high power nonlinear transmission line experiments using LTD technology at UM will be presented.
