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 functi...

The aim of this article is to analyze nonlinear electro-magneto vibration of a double-piezoelectric composite microplate-system (DPCMPS) pursuant to the nonlocal piezoelasticity theory. The two microplates are assumed to be connected by an enclosing elastic medium, which is simulated by the Pasternak foundation. Both of piezoelectric composite microplates are made of poly-vinylidene fluoride (P...

We have studied the magneto-elastic coupling in the double layered Mn perovskite La1.2Sr1.8Mn2O7 with an ultrasonic velocity technique. The temperature profile of both the in-plane and out-of-plane longitudinal velocities showed a large stiffening anomaly below the insulating paramagnetic to metallic ferromagnetic transition. Magnetic fluctuations effects consistent with the layered structure a...

A general and unified theory is formulated to investigate static time-harmonic field solutions induced by dislocation loops arrays in three-dimensional multilayered structures. Each homogeneous plate consists of an orthotropic magneto-electro-elastic material including nonlocal effects. While the constitutive relations with multi-phase coupling are treated means original Eringen model using a H...
