Pulse propagation in inhomogeneous media: modeling wave fields, diffraction, and boundary effects with Green’s functions

This book presents a rigorous look at how waves move through media where properties vary in space. It focuses on constructing Green’s functions to describe pulses, including how boundaries and diffraction shape the signal.

In clear, methodical steps, the work ties together wave equations, boundary conditions, and geometric optics. It shows how to reduce complex propagation problems to solvable forms using transforms and asymptotic methods, with practical guidance for handling shadow regions and diffracted pulses.

• Learn how Green’s functions model disturbances from instantaneous sources in inhomogeneous environments.
• See how boundary conditions and reflections modify wave travel and how to account for shadow regions where direct rays fail.
• Explore the use of Laplace transforms, eigenfunction expansions, and asymptotic techniques to derive approximate solutions.
• Discover connections between rigorous analysis and geometrical optics in diffraction problems.

Ideal for researchers and students working with wave propagation, acoustics, electromagnetics, or any field that models pulses in variable media.
