【 摘 要 】

Coupled propagation of elastic and electromagnetic waves in a piezoelectric / piezomagnetic layered periodic structure with magneto-electro-elastic interlayer is studied using the transfer matrix method. We find that magneto-electro-elastic interlayer can change the elastic wave band gap, electromagnetic wave phase velocity and phonon-polariton band gap position in piezoelectric / piezomagnetic composite structure.
