The Miller Group specializes in design and optimization of wave systems at the micro and nanoscales. We use computation and theory, aiming to open the design space–in photonics, elastodynamics, and more general wave systems–through two approaches: (1) efficiently exploring high-dimensional spaces via large-scale computational optimization, and (2) developing analytical techniques to model new phenomena and discover fundamental response limits. We apply these techniques to application areas including photovoltaics, near-field optics, nanoparticle scatterers, thermal radiation, and more. Our goal is to describe and discover fundamental device performance limits, and to design devices approaching those limits.
