Continuous modal spectrum in nonreciprocal cavities
Filipa R. Prudêncio, David E. Fernandes, Mário G. Silveirinha
Nonreciprocal systems enable asymmetric energy transport and suppress backscattering, giving rise to unconventional wave phenomena. Here, we show that nonreciprocal cavities based…

Plasmonic Time Crystals
Joshua Feinberg, David E. Fernandes, Boris Shapiro +1
We study plasmonic time crystals, an extension of dielectric-based photonic time crystals to plasmonic media. Remarkably, we demonstrate that such systems may amplify both longitud…
