The propagation of Love waves in an orthotropic granular layer under initial stress overlying a semi-infinite granular medium is investigated in this paper. A Fourier transform method has been applied to find the dispersion equation. The dispersion equation is obtained in the form of a ninth-order determinantal expression. The standard equation of dispersion in two-layered isotropic media is deduced as a particular case from this study. The results obtained are displayed graphically and there physical meaning is explained.
