    Coupling between topological edge state and defect mode-based biosensor using phononic crystal by Zaky A. Zaky, M. Al-Dossari, Ahmed S. Hendy, Yassine Bouazzi, Attia Boudjemline, Arafa H. Aly

    Published 2025-01-01
    “…Besides, the salinity of seawater is a crucial factor in understanding its characteristics because any variation in the salinity of seawater represents the variations in the hydrological, biological, and chemical distributions. In this paper, a symmetrical one-dimensional phononic structure is theoretically designed using two symmetrical crystals separated with a defective cavity. …”
