SH wave propagation in a medium having step-shaped discontinuity.

Wave Propagation in Micropolar Thermoelastic Diffusion Medium

The present investigation is concerned with the reflection of plane waves from a free surface of a micropolar thermoelastic diffusion half space in the context of coupled theory of thermoelastic diffusion. The amplitude ratios of various reflected waves are obtained in a closed form. The dependence of these amplitude ratios with an angle of propagation as well as other material parameter are sh...

Wave Propagation in an Inhomogeneous Medium

Wave Propagation in Dielectric Medium Thin Film Medium

Various tools have been employed in studying and computing beam or field propagation in a medium with variation of small refractive index Feit and (Fleck,et al,1976)(Fleck,1978)( Ugwu et al,2007) some researchers had employed beam propagation method based on diagonalization of the Hermitian operator that generates the solution of the Helmholtz equation in media with real refractive indices (Thy...

A fourth-order accurate finite-difference program for the simulation of SH-wave propagation in het- erogeneous viscoelastic medium

This article presents a staggered grid time-domain finite-difference (FD) program for the simulation of sH-wave propagation in a viscoelastic heterogeneous medium. The incorporation of realistic damping in FD program is based on a rheological model widely known as generalized maxwell body (gmB-EK). The accuracy of implementation of realistic damping is validated by comparing the numerically com...

Influence of Heterogeneity on Rayleigh Wave Propagation in an Incompressible Medium Bonded Between Two Half-Spaces

The present investigation deals with the propagation of Rayleigh wave in an incompressible medium bonded between two half-spaces. Variation in elastic parameters of the layer is taken linear form. The solution for layer and half-space are obtained analytically. Frequency equation for Rayleigh waves has been obtained. It is observed that the heterogeneity and width of the incompressible medium h...
