Computer modeling is a key tool in understanding wave phenomena in nature. It is used for instance in seismology for exploring the consequences of the Earth's fine structure and in electromagnetism for modeling of radar and micro- wave signals. Iterative, model driven estimation of material structure and constitutive parameters in an oft-proposed application of computer modeling, but requires very fast simulations to achieve its potential. These simulations are computationally challenging especially in three dimensions. This project studied a variety of approaches to improving the efficiency and fidelity of wave simulations. It also developed a basic software approach to material parameter estimation. This software is designed, for example, to assis in the interpretation of Ground Penetrating Radar data for civil and environmental engineering applications.
