Absence of unidirectionally propagating surface plasmon-polaritons at nonreciprocal metal-dielectric interfaces

The local Drude model predicts that, under certain conditions, surface plasmon polaritons at a metal-dielectric surface have a frequency range where only unidirectional propagation is supported. Here, the authors show that in more realistic non-local models surface plasmon polaritons exhibit bidirec...
