Dosimetric characterization of a nanophotonic scintillator and applications to real-time in-vivo total body irradiation dosimetry
W. Jeffrey Zabel, Dixin Chen, Louis Martin-Monier +7
Purpose: Recent advances in metasurface photonics and manufacturing have enabled a nanophotonic surface coating to be applied to conventional scintillators, which has been shown to…
Diffractive cascades for polychromatic hard X-ray focusing
William Michaels, Simo Pajovic, Joshua Chen +2
Diffractive focusing of hard X-rays has traditionally required structures with large aspect ratios due to the limited interaction of most materials with X-rays. This has increased…
Visible-NIR-Frequency Hyperbolic Response in Nodal-Line Semimetal PbTaSe
Vivian J. Santamaria-Garcia, Morgan G. Blevins, Simo Pajovic +2
Natural hyperbolic materials offer a powerful platform for light-matter interactions by supporting highly anisotropic electromagnetic modes without the need for artificial patterni…
Wavefront Engineering for Scintillation-Based Imaging
Joshua Chen, Sachin Vaidya, Simo Pajovic +7
Recent research in nanophotonics for scintillation-based imaging has demonstrated promising improvements in scintillator performance. In parallel, advances in nanophotonics have en…
Breakdown of the Kirchhoff's law of thermal radiation by a spatiotemporally modulated nonreciprocal metasurface
Anatoly Efimov, Chun-Chieh Chang, Simo Pajovic +5
Kirchhoff's law of thermal radiation, which dictates that the emissivity of a surface equals its absorptivity under thermal equilibrium, which dictates that the emissivity of a sur…
End-to-end design of multicolor scintillators for enhanced energy resolution in X-ray imaging
Seokhwan Min, Seou Choi, Simo Pajovic +5
Scintillators have been widely used in X-ray imaging due to their ability to convert high-energy radiation into visible light, making them essential for applications such as medica…
