A semi-analytical Fourier-series analysis was made of the elastic field of a dislocation that was located along an interfacial ledge. The analysis was based upon a discretization of the stress and displacement boundary conditions along the interface. This required the solution of a system of linear equations which described the elastic coupling between the 2 media.
