Investigation of beam splitter in a zero-refractive-index photonic crystal at the frequency of Dirac-like point
The Dirac-like cone dispersion of the photonic crystal induced by the three-fold accidental degeneracy at the Brillouin center is calculated in this paper. Such photonic crystals can be mapped to zero-refractive-index materials at the vicinity of the Dirac-like point frequency, and utilized to const...
