The American collaborators have an extensive experience in the mathematical and numerical analysis of direct and inverse scattering problems, as well as in the design and analysis of efficient artificial absorbing boundary conditions. The French researchers of Magique-3D are applied mathematicians who are mainly interested in solving problems arising in geophysical applications using ideas and techniques developed in the field of scattering problems. The proposed international cooperation is unique because the investigator backgrounds, research interests, and technical skills complement to form a truly interdisciplinary team with a potential for significant impact on the computational infrastructure of science and engineering. Several of the US and french investigators have already worked together and visited each other, and therefore are familiar with each other’s work. Moreover, this proposed collaboration provides graduate students, post-doctoral assistants and faculty the opportunity to be exposed to different modes of thinking, a different work environment as well as a different culture, and therefore will provide an excellent training for succeeding in an increasingly global environment.
