Microwave Magnetic Thin Film Soliton Device Physics
Abstract
ARO Grant DAAH04-95-1-0325 (P-33936-PH) has supported a research program to explore and implement concepts which utilize microwave magnetic envelope solitons in thin magnetic film device configurations for signal processing at microwave and millimeter wave frequencies. The work has produced various versions of a soliton oscillator, a soliton switch, and a soliton parametric amplifier. The work has also spawned a number of new device concepts, including an active delay line, several versions of a bistable oscillator, a decay free soliton train generator, and a mode locked spontaneous soliton generator. The switch concept has evolved into a simple phase sensitive on/off switch and a multi-port switch based on the self focusing properties of beam solitons. The original parametric amplifier idea, with the soliton transducer structure inside a microwave cavity, has evolved into a microstrip resonator device with localized parametric pumping and gains in excess of 29 dB. This represents a major breakthrough for magnetic film microwave devices. Work has also proceeded on the study of soliton formation, propagation, reflection, and interaction. A second major breakthrough has been achieved in the direct detection of microwave solitons in magnetic films by Brillouin light scattering.
