Item description for Higher-Order Numerical Methods for Transient Wave Equations by Gary Cohen...
Solving efficiently the wave equations involved in modeling acoustic, elastic or electromagnetic wave propagation remains a challenge both for research and industry. To attack the problems coming from the propagative character of the solution, the author constructs higher-order numerical methods to reduce the size of the meshes, and consequently the time and space stepping, dramatically improving storage and computing times. This book surveys higher-order finite difference methods and develops various mass-lumped finite (also called spectral) element methods for the transient wave equations, and presents the most efficient methods, respecting both accuracy and stability for each sort of problem. A central role is played by the notion of the dispersion relation for analyzing the methods. The last chapter is devoted to unbounded domains which are modeled using perfectly matched layer (PML) techniques. Numerical examples are given.

Reviews - What do customers think about Higher-Order Numerical Methods for Transient Wave Equations?
A must have ! May 12, 2005
If you are studying this subject on your own and there are no one to help you with your work this is the book, you should have. This book explains the subjects to you as if your classmate is explaining them. The writer goes directly to the important sections of the subjects and doesn't deal with unnecessary details. The language he uses is perfect. There could have been some code samples but the solved examples can give you an idea on how you are going to code.
share beautiful ideas with the book Mar 31, 2005
This is a greak book which gives you a deep insight to understand high order numerical methods for wave equations. Read it, you will be suprised at the beautiful ideas of mass lumping and the elegant basis functions constructed for spectral element methods. The author is a genius and construcs several innovative basis functions for both hexahedral and tetrahedron elements. The only shortage is that it is not very detailed in some advanced topics. You may need to figure them out by yourself.
