Information transduction based on magnons

摘要: We present an information transduction architecture that utilizes coherent interconversion between photons, magnons and electric charge carriers. The materials we use are low loss magneto-optic yttrium iron garnet (YIG). This device platform enables high fidelity communication devices, as well small size microwave signal processing devices for Radar and defense related applications. Specific examples given here widely tunable oscillators, variable low delay lines, Q line oscillators.
