Abstract

A Force-Mode Distributed Wave Oscillator (FMDWO) that provides accurate multiple phases of an oscillation, a Force Mode Distributed Wave Antenna as a radiating element, a Force-Mode Distributed Oscillator Amplifier (FMDOA) and an array of amplifiers capable of operating as a beam forming phased-array antenna driver. Two distinct force mode mechanisms, one delay-based and the other geometry-based, utilizing inverter amplifiers, inject an oscillation on independent conductor loops or rings via transmission lines forming a differential transmission medium for the oscillation wave. Once the oscillation wave is initiated through the forcing mechanisms, the oscillations continue uninterrupted independent of any external triggering.
