Exceptional point empowered near-field routing of hyperbolic polaritons

A PT-symmetric non-Hermitian photonic system composed of specifically designed metal structures is used to conduct arbitrary polarization transition from the equator and generate polarization vortices with exceptional point on the Poincaré sphere’s poles, which induces unidirectional hyperbolic pola...

Description
Summary:A PT-symmetric non-Hermitian photonic system composed of specifically designed metal structures is used to conduct arbitrary polarization transition from the equator and generate polarization vortices with exceptional point on the Poincaré sphere’s poles, which induces unidirectional hyperbolic polaritons propagation due to the break of mirror symmetry.
