radiation has played an important role in incandescent lamps, solar
energy utilization, temperature measurements, materials processing,
remote sensing for astronomy and space exploration, combustion and
furnace design, food processing, cryogenic engineering, as well as
numerous agricultural, health, and military applications. Recent
studies have shown that the near-field effects can realize emerging
technologies, such as superlens, sub-wavelength light source,
polariton-assisted biosensors, and energy conversion devices.
Because of the important applications to energy transport and
conversion, the study of engineered surfaces with desired thermal
radiative characteristics using controlled micro/nanostructures has
emerged as a new frontier in thermophysics and radiative transfer
research. The objective of our research
group is to investigate the fundamental mechanisms of thermal radiation
and to design and fabricate suitable micro/nanostructures for emerging technologies
such as nanoelectronics, microscale thermophotovoltaic devices, nanothermal manufacturing, surface thermal metrology, and biotechnology. We investigate radiative energy conversion devices for power generation and refrigeration, as well as spectral absorptance of particles for solar energy harvesting.
