S-H type waves un a sandwiched spherical model

Abstract

Propagation of S-H type waves in a heterogeneous spherical layer (the density, p, anda modulus of rigidity µ vary inversely as the square of the radial distance, r, as measured from the center, such that shear wave velocity is constant) are held between a homogeneous spherical crust and a homogeneous spherical core, the period equations are deduced and their propriety is established numerical results considering the central core is (1) solid and (2) fluid.
