Anti-reflection coatings for highly anisotropic materials in the mid infrared
Hongyan Mei, Jin-Woo Cho, Jae-Seon Yu +6
We develop and optimize thin anti-reflection coatings (ARCs) for highly anisotropic materials in the mid infrared. Unlike conventional ARCs that assume nearly isotropic refractive…

Preventing overfitting in infrared ellipsometry using temperature dependence: fused silica as a case study
Shenwei Yin, Jin-Woo Cho, Demeng Feng +6
Fitting oscillator models to variable-angle spectroscopic ellipsometry (VASE) data can lead to non-unique, unphysical results. We demonstrate using temperature-dependent trends to…

Passive radiative cooling using temperature-dependent emissivity can sometimes outperform static emitters
Yeonghoon Jin, Jin-Woo Cho, Mikhail A. Kats
In passive sky-facing radiative cooling, wavelength-selective thermal emitters in the atmospheric transparency window of 8-13 m can reach lower temperatures compared to broadba…
