Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

Despite their engineering significance, locally resonant metamaterials are facing the
challenge to cope with the need for broad-range band gap adjustment at low-frequencies …

The topological state in photonics was first realized based on the magnetic-optic (MO) effect
and developed rapidly in recent years. This review summarizes various topological states …

The elastic analogs of topological insulators (TIs) have attracted substantial research
