Abstract

Non-reciprocal devices have played a crucial role in photonic and microwave applications. Conversion of polarization state of light, unidirectional light propagation emerge due to various symmetry reductions. In the first part of my talk I will propose a design for unidirectional leaky meta-waveguide based on Fano resonant metasurfaces deposited on top of ferrite. Later I will talk about Klein tunneling in photonic graphene, the unimpeded transmission of massless particles through a potential barrier owing to their Dirac-like dispersion.
