Theoretical Investigation of Magneto-Electro-Elastic Piezoelectric Phononic Crystal

We design a magneto-electro-elastic piezoelectric phononic crystal (MPPC) using one-dimensional superlattice (with 3m point group) and split-ring resonators. The effect of the resonators is to enhance superlattices. This will create elastic anomalies generate band gaps. These are first proposed theoretically. calculate transmission function MPPC through Transfer Matrix Method crystal. By function, we theoretically study propagation properties acoustic waves in MPPC. mechanism for multifield coupling analyzed. A type gap created, called gap. analyze possibility crystals as left-handed metamaterials. also discuss some potential applications.
