Near optimal graphene terahertz non-reciprocal isolator

Optical isolators, or optical diodes, allow electromagnetic radiation to travel in one direction but not the other. Here, the authors achieve unidirectional propagation of terahertz waves by taking advantage of the non-reciprocal nature of optical conductivity in magnetostatically biased graphene.
