摘要：
We demonstrate that a symmetry protected topological (SPT) state can be engineered in a three-dimensional (3D) all-dielectric metacrystal where the electromagnetic duality between electric and magnetic fields is ensured by the meta-atoms design. Magneto-electric coupling results in a complete topological photonic bandgap and an emergence of spin-polarized surface states with conical Dirac dispersion on 2D topological domain walls.
