Abstract
THE properties of non-linear transmission lines, containing, for example, ferroelectric material of the barium titanate class, have been examined, in connexion with a computing system1. Their possible use as a variable capacity parametric amplifier element is obvious, and it has been shown recently that an electromagnetic shock-wave can be propagated2. This effect occurs when a signal of large amplitude is injected into the line. The high-field part of the wave travels at a greater speed than the low-field part so that a sine wave becomes a saw-tooth. After a certain time this has a vertical leading edge analogous to a shock-wave in a gas. Such a wave is rich in harmonics and a number of lines, driven with power derived from the same microwave magnetron and with outputs recombined through phase shifters, could be an efficient harmonic generator.
