Background:
John A. DeSanto received his B.S. (Physics) and M.A. (Mathematics)
from
Villanova University and his M.S. and Ph.D. (Physics)
from the University of
Michigan. He held Woodrow Wilson and National Science Foundation
Fellowships
at the University of Michigan. Before joining the Colorado School
of Mines in
1983 he was employed at the Naval Research Laboratory in Washington,
D.C.,
Electromagnetic Applications Incorporated, and the University
of Denver. He is
a professor in the Department of Mathematical and Computer Sciences.
DeSanto has authored 80 research papers in classical wave
theory, most notably
sound propagation in the ocean and the scattering of acoustic
and
electromagnetic waves from rough surfaces. He has edited (Ocean
Acoustics),
coedited (Mathematical Methods and Applications of Scattering
Theory), and
authored (Scalar Wave Theory) books published by Springer, and
edited
(Proceedings of the Fourth International Conference on Mathematical
and
Numerical Aspects of Wave Propagation) published by SIAM. He
is a Fellow of
the
Acoustical Society of America and a member of several other
technical
societies. He wrote the Ocean Acoustics chapter in the Encyclopedia
of
Physics (3rd Edition, Ed. by R.M.Besancon). He has received several
honors
and a guest lectureship at Woods Hole. He has recently held Fulbright
and
National Research Council Fellowships and was Professeur Invite
at the
Laboratoire d'Optique Electromagnetique, University AixMarseille
III in 1993.
DeSanto's technical work has been sponsored by the Office
of Naval Research,
the Naval Research Laboratory, the Naval Underwater Systems Center, the
U.S.
Army Research Office, and presently, the Air Force Office of
Scientific
Research for research on electromagnetic scattering from rough
surfaces.
DeSanto's theoretical and computational work includes both
direct and inverse
scattering from rough surfaces. The major focus has been to find
the fastest
and most reliable computational technique to describe the direct
scattering,
and to determine the parameter space within which rough surfaces
can be
reconstructed from data. He is responsible for several research
developments
in surface scattering, among them the development of combined
Feynman diagram
and partial summation techniques in spectral space for acoustic,
elastic
and electromagnetic scattering
from rough surfaces, the application
of
combined physical optics/Fourier expansion techniques for scattering
from
gratings, the development of mixed coordinate and spectral scattering
theories,
and highly accurate surface inversion techniques using his spectralcoordinate
method. He also is responsible for a method to rigorously relate
the solutions
of the Helmholtz equation to
those of a parabolic equation for
waveguide
propagation.
