    This study investigated the time-evolved photonic Bloch oscillations (PBOs) in a multi-layered fishnet structure (MLFS) with both a negative refraction index (NRI) and a positive refraction index (PRI) at different transmission bands. The PBOs in MLFS are generated by the Bragg reflection and...
