Paper Abstract

Several current attempts to use acoustic and electromagnetic wave propagation for modeling physical phenomena and the role that wavelet analysis is playing in these efforts are discussed. The first probem involves the recent application of wavelets to computational fluid dynamics. The second problem involves geophysical modeling of the ocean floor, using acoustic waves, and wavelets have recently been shown to play an important role here already. The third problem involves modeling of synthetic aperture radar (SAR) images in the context of automatic target recognition efforts. The fourth problem is global illumination in computer graphics, i.e., simulation of reflected and absorbed light for everyday environments. The role of wavelets is more embryonic in the last two areas, but there are some common principles in all of these modeling efforts, and the methodology of wavelets seems well suited to certain aspects of these problems.
