| Research Abstract |
This work involves the imaging and control of phonon modes confined in a wide variety of novel microscopic geometries with unprecedented picosecond temporal, micron spatial, and megahertz frequency resolutions. The following topics are investigated : visualizing Bloch waves and modes in phononic crystals, phononic crystal waveguides and cavities, investigating whispering gallery modes, acoustic negative refraction, and phase singularities in surface acoustic wave fields, and applications to industrially-produced surface acoustic wave resonators. Visualization and Mode-Control of Phonons Confined in Microstructures
