Scalar Wave Theory

This monograph is an excellent introduction to the mathematical techniques used to describe the scattering and propagation of scalar waves, in particular sound waves. The scalar wave equations and Green's functions are developed from fundamental principles and to the following main problems: plane wave and spherical wave from flat interfaces, and propagation in a two-layer liquid half-space (Pekeeris waveguide). The detailed discussion facilitates extension of the techniques to real situations.
