Mid-infrared analogue polaritonic reversed Cherenkov radiation in natural anisotropic crystals
Abstract Cherenkov radiation (CR) excited by fast charges can serve as on-chip light sources with a nanoscale footprint and broad frequency range. The reversed CR, which usually occurs in media with the negative refractive index or negative group-velocity dispersion, is highly desired because it can...
