thermal radiation and appears colder on an infrared camera. Our experimental approach allows for a direct measurement and extraction of wavelength- and temperature-dependent thermal emittance. We anticipate that emissivity engineering with thin-film geometries comprising VO2 and other thermochromic materials will find applications in infrared camouflage, thermal regulation, and infrared tagging and labeling.

- Optical absorbers based on strong interference in ultra‐thin films (2016, background): “Tailored thermal emitters have a wide variety of applications, including infrared scene generation, thermal signature masking [84], and wavelength-selective thermal light sources [92], which are especially useful for thermo-photovoltaics [93].”
- A review of gap-surface plasmon metasurfaces: fundamentals and applications (2018, background): “As such, vanadium dioxide (VO2), a classical transition metal oxide that behaves as an insulator and metal at temperature below and above the insulator-to-metal transition temperature (~340 K in bulk crystals), respectively, is a good choice to facilitate reconfigurable GSPMs [166, 177, 178].”
- Phonon-polaritonics: enabling powerful capabilities for infrared photonics (2019, background): “Phase-change material (PCM), such as VO2 [107, 299] and GST [200, 201], are gaining increased attention as photonic materials.”
