    Talk Title: Thermal-emission engineering: challenges and opportunities

    Abstract: Thermal emission (thermal radiation) is the phenomenon responsible for most of the light in the universe. Though understanding of thermal emission dates back over a century, recent advances have encouraged the re-examination of this phenomenon and its applications. This talk will describe our groups advances and outline future work in the measurement and manipulation of thermal emission. First, I will discuss our efforts to improve thermal-emission metrology, especially for low-temperature thermal emitters, emitters with temperature-dependent emissivity, and emitters out of equilibrium. Then, I will describe our use of phase-transition materials including vanadium dioxide and rare-earth nickelates to demonstrate new phenomena, including negative- and zero-differential thermal emittance, radiative thermal runaway, and thermo-dichroism. I will also discuss our recent demonstration of nanosecond-scale modulation of emissivity and thermal-emission pulses down to picosecond scales. The talk will include discussion of exciting opportunities of thermal-emission engineering for infrared camouflage and thermoregulation.
