A new nanomaterial of minuscule gold rods embedded in glass manipulates light passing through it like no naturally occurring substance (Opt. Lett. 2005, 30, 3356). Potential payoffs, say the Purdue ...

The work was published in Science ("Gate-tunable negative refraction of mid-infrared polaritons"). Basic principle of the “polariton transistor”. The van der Waals heterostructure is constructed by ...
