IM8
Boundary Integral Methods for Selected Wave-Propagation Problems

10:15 AM-12:15 PM
Room 246

Problems in applied mathematics and physics involving propagation of acoustic, elastic, and electromagnetic waves are important in a number of disciplines, among which is nondestructive evaluation (NDE).

The speakers in this minisymposium discuss the formulation and numerical solution of some representative wave problems via the vehicle of boundary integral equations. They will discuss problems involving electromagnetic phenomena and ultrasonic waves dealing with problems in unbounded domains via boundary methods, analytical and numerical issues which arise in connection with singularities in the integral equations, and the presence of boundaries of indefinite extent, such as a halfspace surface.
