Wave scattering by PT-symmetric epsilon-near-zero periodic structures
Oksana Shramkova, Giorgos Tsironis
The optical properties of PT-symmetric epsilonnear-zero (ENZ) periodic stack of the layers with balanced loss and gain have been examined. The effect of periodicity on the unidirec…

Nonreciprocal Scattering by PT-symmetric stack of the layers
Oksana Shramkova, Giorgos Tsironis
The nonreciprocal wave propagation in PT-symmetric periodic stack of binary dielectric layers characterised by balances loss and gain is analysed. The main mechanisms and resonant…
