Diffraction in Inhomogeneous Media presents a clear, accessible path from ordinary geometrical optics to a powerful extension that handles shadows. It shows how new rays, including diffracted and complex ones, illuminate how waves propagate when boundaries and inhomogeneities matter. The book links theory to exact and asymptotic solutions, illustrating how to calculate fields in tricky settings like plane stratified media and cylinders. It’s structured in two parts: a theory section and a boundary-value problem approach that checks results against exact solutions.

Learn how to define and trace diffracted rays, including how surface rays split and rejoin with ordinary rays.
See how boundary conditions and impedance influence reflection, transmission, and the diffracted field.
Explore how asymptotic methods match exact solutions across scenarios like plane stratified media and cylindrical boundaries.
Understand the role of complex or imaginary rays and how they contribute to the overall field.

Ideal for readers seeking a practical, theory-grounded approach to wave propagation in inhomogeneous media, and for those who want methods that work well beyond simple, uniform materials. This edition is a helpful reference for advanced students and professionals in physics and engineering working with diffraction, scattering, and waveguides.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
