Topological photonic states, inspired by robust chiral edge states in topological insulators, have recently been demonstrated a few systems, including an array of coupled on-chip ring resonators at communication wavelengths. However, the intrinsic difference between electrons and photons determines that protection time-reversal-invariant systems does not share same robustness as its counterpart electronic insulators. Here, designer surface plasmon platform consisting tunable metallic sub-wavelength structures, we construct probe their against variety defect classes, some common defects can break protection, but do exist This is also first experimental realization anomalous Floquet whose phase cannot be predicted usual Chern number invariants.
