Selective Radiative Heating of Nanostructures Using Hyperbolic Metamaterials
Ding Ding, Austin J. Minnich
Hyperbolic metamaterials (HMM) are of great interest due to their ability to break the diffraction limit for imaging and enhance near-field radiative heat transfer. Here we demonst…
Cross-plane heat conduction in thin solid films
Chengyun Hua, Austin J. Minnich
Cross-plane heat transport in thin films with thickness comparable to the phonon mean free paths is of both fundamental and practical interest. However, physical insight is difficu…
