Edge states in self-complementary checkerboard photonic crystals: Zak phase, surface impedance and experimental verification

, 2017
Edge states of photonic crystals have attracted much attention for the potential applications such as high transmission waveguide bends, spin dependent splitters and one-way photonic circuits. Here, we theoretically discuss and experimentally observe the
