Abstract
This paper is concerned with developing methods for the propagation of linear waves in several space dimensions. The methods are time revers ible and hence are free from numerical dissipation. They are based on bicharacteristic forms of the governing equations and are made possibl e by adopting forms of staggered storage that depend on the precise eq uations under consideration. Analysis is presented for the equations o f acoustics, electromagnetics, and elastodynamics.
