A method for determining the radiation characteristics of an SH-wave line source embedded in a layered medium having rough interfaces is herein described. The presented technique utilizes the plane-wave spectral decomposition of the relevant fields in the framework of the extended boundary condition method. It is also shown how the equations derived for the general case reduce considerably when the interfaces are periodically rough. Extensions of the problem solved here have been briefly mentioned, and the presented solution technique should find application in several areas involving the propagation of elastic waves.
