Abstract:
The advancement of nanotechnology has enabled precise manufacturing of structures with feature sizes smaller than the characteristic wavelength of thermal radiation. Tailoring thermal radiative properties using micro-/nano-structured surfaces has drawn much attention due to potential applications in energy conversion devices, space thermal management, and infrared radiation detection. It has been demonstrated that thermal radiative properties can be spectrally and/ or directionally controlled by exploiting electromagnetic resonance phenomena, such as surface plasmon and magnetic resonance, on structured surfaces. This presentation will address the fundamentals of electromagnetic resonance phenomena on sub-wavelength nanostructures and will provide some insights on the application of designed nanostructures in energy harvesting (e.g., photovoltaic and solar thermal devices). The second part of the presentation will introduce the design of a blended plasmonic nanofluid having broad-band absorption characteristic in the visible and near-infrared spectral region and its application to a volumetric solar thermal absorber.
