Numerical Simulation of Wave Propagation
Abstract: The interaction of waves (acoustic, electromagnetic, elastic) with layered
media plays an important role in many scientific problems. Among these are
seismic imaging, underwater acoustics, biosensing, and solar cells. The
ability to simulate scattered fields from these structures in a robust and
highly accurate fashion is of fundamental importance. In this talk we will
describe a class of rapid and highly accurate boundary perturbation schemes,
termed ``High--Order Perturbation of Surfaces'' (HOPS) Methods, for
delivering such numerical approximations. Time permitting we will describe
our efforts to not only detect layered media geometries based upon far--field
data, but also design these structures to have optimal scattering properties.
