Abstract: The
propagation path from a source to a field point in
presence of an obstacle, such as an aircraft, can be
very complex. In particular, the contact set of the
path with the obstacle is a piece of geodesic in the
metric of the obstacle. If the propagation path is
known then the highfrequency contribution to the
field (due to that path) can be calculated by
"gluing" together local scattering properties of the
obstacle along the path. By contrast, determination
of propagation paths is a global problem in
geometry. In my talk I plan to discuss a
computational approach to a solution of this problem
and integration of this solution with high frequency
electromagnetics methods.
