Text of Note

The theory of propagation of spherical waves in layered media is presented in this companion volume to the successful Acoustics of Layered Media I, which covers plane wave propagation. Acad. Brekhovskikh and Dr. Godin have been mathematically rigorous, but have kept a constant eye on the physical usefulness and logic of the theory, in application to both natural (e.g. geological) and manmade structures. Both moving and stationary media, discretely and continuously layered, are treated for various types of acoustic wave sources. Detailed appendices provide further background on the mathematical methods.
