Though understanding of thermal radiation dates ba ck over a century\, recent advances have encouraged the re-examination of this phenomenon and its applications. This talk will describe our group’ s advances and outline future work in the measurement and manipulation of thermal radiation. First\, I will discuss our innovations in thermal-radia tion metrology\, especially for low-temperature thermal emitters\, emitter s with temperature-dependent emissivity\, and emitters out of equilibrium. Such improvements can enable techniques such as our recently demonstrated technique of depth thermography\, in which measurements of thermal radiat ion yield temperature information below the surface of objects. I will als o describe our invention of a minimalistic spectroscopy technique that req uires no gratings\, interferometers\, or any other wavelength-selective co mponents. Then\, I will describe the use of phase-transition materials inc luding vanadium dioxide and rare-earth nickelates to demonstrate new pheno mena\, including negative- and zero-differential thermal emittance. I will also discuss our recent demonstration of nanosecond-scale modulation of e missivity and thermal-radiation pulses down to picosecond scales. The talk will include discussion of exciting opportunities of thermal-radiation en gineering for infrared-privacy and thermoregulation technologies.\n\nSpeak er(s): Prof. Mikhail A.
