Abstract
The light-matter interaction in two-dimensional photonics crystals occur, primarily, via formation of polaritons, quasi-particules with sub-drifractional wavelength associated to material resonances like vibrations and free charge waves. In this investigation, we will study plasmons-polaritons of graphene (G), phonon-polaritons of hexagonal boron nitride (hBN) and theplasmon-phonon-polari…
