Bandgap closure in 1D photonic crystals from interplay between Mie resonances
In this work, we study a 1D silicon photonic formed by a set of silicon nanobricks, which supports a Bragg photonic bandgap (PBG) for TE-like polarization. We show that the Bragg PBG can vanish because of the interplay between the electric and magnetic dipole of its constituent silicon nanobricks.
