PT-symmetry-induced wave confinement and guiding in ε-near-zero metamaterials
Inspired by the parity-time symmetry concept, we show that a judicious spatial modulation of gain and loss in ε-near-zero metamaterials …

Optical isolation via unidirectional resonant photon tunneling
We show that tri-layer structures combining epsilon-negative and magneto-optical material layers can exhibit unidirectional resonant …

Tunneling of obliquely incident waves through PT-symmetric epsilon-near-zero bilayers
We show that obliquely incident, transversely magnetic-polarized plane waves can be totally transmitted (with zero reflection) through …

Enhanced Faraday rotation via resonant tunnelling in tri-layers containing magneto-optical metals
We study resonant tunnelling effects that can occur in trilayer structures featuring a dielectric layer sandwiched between two …
