An analytical approach is applied to study the propagation of Love-type waves in an orthotropic substratum over a porous half-space. A heterogeneous orthotropic layer is bonded to a porous half-space in such a way that the interface between these two elastic mediums is corrugated type. Methods of applied mathematics have been employed in dealing with the equation of motion to obtain the dispersion equation in closed form. The study focuses especially on the effect of corrugated type interface between two medium, along with porosity, heterogeneity, and initial stress, affect the velocity profile. The effects of corrugation and elastic parameters on the velocity profile of Love-type waves are discussed using graphical representation. © 2018 by Begell House
