My research will be characterized by the following theme: understand electromagnetic properties of nanoscale materials, near-field effects on radiative transfer, control of far-field thermal radiation with periodic structures, and applying the results to conversion of thermal radiation, such as solar radiation, to electric or chemical energy.
- Theoretical investigation of electromagnetic near-field interaction between two spheres and between a sphere and a flat substrate.
- Usage of dyadic Green’s functions in electromagnetic scattering problems, nano-optics, and near-field thermal radiation.
- Refinement of an experimental technique (developed by Arvind Narayanaswamy and Gang Chen at MIT) to measure near-field thermal radiative exchange.
- Experimental investigation of near-field thermal radiative exchange between a sphere and flat substrate or another sphere.
- Investigating the dynamics of bi-material AFM cantilevers.
- Theoretical and experimental investigation of spectrally selective emission from periodic structures.
