Abstract:

Photonic metamaterials with advanced optical and thermal functionalities have capability of active light manipulation and dynamic tuning nanoscale thermal transport. There is a constant need of functional metamaterials with (a) an excellent spectral selectivity for thermophotovoltaics and thermoelectric systems, (b) an efficient self-adaptivity for energy conversion and cooling, and (c) an ultrahigh and tuneable rectification ratio for thermal management and logic devices. My research is to conduct a fundamental study of functional metamaterials with tunable wavelength selectivity, self-adaptive feature, and strong thermal switching performance while taking the advantages of the scattering of multi-species nanoparticle inclusions, phase transition, and reconfigurable structures. This seminar aims to enlighten how to fundamentally explore the multifunctionalities of cost-effective metamaterials and dynamic tuning of radiative thermal transport, and their applications to passive radiative cooling, thermal rectification, and solar-driven water desalination.
