Mid-infrared analogue polaritonic reversed Cherenkov radiation in natural anisotropic crystals

Posted by in category: materials

Here, the authors demonstrate an analogue reversed Cherenkov radiation at mid-infrared frequencies in MoO3, a natural hyperbolic material, and show that the radiation angle and the quality factor can be increased by stacking hBN layers on the MoO3 surface.
