Abstract
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 unidirectional tunneling phenomenon and symmetry breaking is determined. The performed analysis provides insight in the main features of the second harmonic (SH) generation by the ENZ PTsymmetric periodic structure.
