Dispersion of Shear Waves in an Irregular Magnetoelastic Self-Reinforced Layer Sandwiched between two Isotropic Half-Spaces

In the present paper we study the propagation of SH waves in an internal magnetoelastic self-reinforced stratum, with rectangular irregularity in lower interface, sandwiched between two semi-infinite isotropic elastic medium. The dispersion equation has been obtained. It is observed that the dispersion equation is in assertion with the classical Love type wave equation, for isotropic layer sandwiched between two isotropic half spaces, in the absence of reinforcement, magnetic field and irregularity. The effect of different depth of irregularity and different values of magnetoelastic coupling parameter on dispersion curves are depicted by means of graphs. This study shows the remarkable effect of wave number, size of irregularity and magnetic field on the phase velocity.
