Congratulations Alyssa Livingood, NSF REU fellow 2019, on being FIRST AUTHOR on a published paper in ACS Photonics! Being a first author on a paper is a major accomplishment and we at VINSE are very proud of Alyssa’s accomplishment. Alyssa is currently studying to receive her B.S. in Computer Engineering at the University of Kentucky.
“Filterless Nondispersive Infrared Sensing using Narrowband Infrared Emitting Metamaterials” was published from the Caldwell lab.
The project focused on demonstrating the use of cadmium oxide films for a narrowband, normal incidence nanophotonic IR emitting metamaterial (NIREM). Through a collaboration with Third Floor Materials, it was demonstrated that the radiation pattern could be changed by growing on a patterned sapphire substrate, while enabling a narrow bandwidth. This was demonstrated as a potential plug and play replacement for non-dispersive IR (NDIR) gas sensing of CO2!
