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.
This book comprises some of the lecture notes I developed for various one-or two-semester courses I taught at the Colorado School of Mines. The main objective of all the courses was to introduce students to the mathematical aspects of wave theory with a focus on the solution of some specific fundamental problems. These fundamental solutions would then serve as a basis for more complex wave propagation and scattering problems. Although the courses were taught in the mathematics department, the audience was mainly not mathematicians. It consisted of gradu ate science and engineering majors with a varied background in both mathematics and wave theory in general. I believed it was necessary to start from fundamental principles of both advanced applied math ematics as well as wave theory and to develop them both in some detail. The notes reflect this type of development, and I have kept this detail in the text. I believe it essential in technical careers to see this detailed development at least once. This volume consists of five chapters. The first two on Scalar Wave Theory (Chapter 1) and Green's Functions (Chapter 2) are mainly mathematical although in Chapter 1 the wave equation is derived from fundamental physical principles. More complicated problems involving spatially and even temporally varying media are briefly introduced."
This detailed introduction to the mathematical techniques used to describe the scattering and propagation of scalar waves will be of particular interest to researchers in the fields of acoustics and mathematical physics.
