Passive & Active Control of Regenerative Standing & Soliton Waves

This paper reviews two technologies that govern the character of electromagnetic waves, or wave-control technologies, that we recently developed (Andress and Ham, 2005) and (Ricketts et al., 2006) in the context of wave-based oscillators. In (Andress and Ham, 2005), the component fields of a standing wave hosted by a transmission line are sculpted to better suit the unique standing wave properties; this passive wave control is achieved by tapering the transmission line along its length and serves to reduce the oscillator phase noise. In (Ricketts et al., 2006) we constructed an oscillator that self-generates a stable, periodic train of electrical solitons. In this work, an active amplifier controls the "unruly" soliton dynamics to guarantee oscillation stability
