    • Phase Transition in PT Symmetric Active Plasmonic Systems 
      Mattheakis, Marios; Oikonomou, Thomas; Molina Gálvez, Mario; Tsironis, George P. (IEEE, 2016)
      Surface plasmon polaritons (SPPs) are coherent electromagnetic surface waves trapped on an insulator-conductor interface. The SPPs decay exponentially along the propagation due to conductor losses, restricting the SPPs ...
