DIFFRACTION OF MAGNETOELASTIC WAVES BY PIEZOELECTRIC NANOFIBER EMBEDDED IN PIEZOMAGNETIC MATRIX

Abstract

We present an analytical method for the scattering of antiplane shear waves by a piezoelectric nanofiber surrounded by piezomagnetic matrix. Owing to their analogies, the piezoelectric surface/interface theory is extended to the magneto-electro-elastic surface/interface theory. The analytical solutions of elastic field, electric field and magnetic field are expressed by employing wave function expansion method and then the expanded mode coefficients are determined by satisfying the nanoboundary conditions around the fiber (a piezoelectric nanowire). The effects of the incident frequency are graphically illustrated and discussed. The material properties of the nanointerface, which is related to the two phases, are examined through parametric variation. A comparison with a non-nano case is also presented.
