wave basis functions a b s t r a c t We consider the scattering of a time-harmonic acoustic incident plane wave by a sound soft convex curvilinear polygon with Lipschitz boundary. For standard boundary or finite element methods, with a piecewise polynomial approximation space, the number of degrees
## Abstract A triaxial ellipsoid of unknown position, size and orientation is located somewhere in space. Highβfrequency asymptotics for the scattering amplitude and the sojourn time for the travelling of a highβfrequency acoustic plane wave are utilized to determine the position of a supporting pl
