Super-collimation and negative refraction in hyperbolic Van der Waals superlattices
In this paper, we investigate supercollimation and negative group refraction properties of Van der Waals crystals. Van der Waals crystals, such as Bi 2 Se 3 , show both type I and type II hyperbolic dispersion at terahertz (THz) frequencies. An all angle negative group index of refraction is observe...
