LOW FREQUENCY SCATTERING FROM AN OGIVE.

Abstract

By means of a method developed, it is now possible to solve iteratively the Dirichlet problem for the scaler Helmholtz equation in the regions exterior to a non-separable body imbedded in the Euclidean 3-space provided (1) k, the complex wave number, is sufficiently small, and (2) the solution of the potential Dirichlet problem for the body in question is known. In the present work we consider the low frequency scattering of a plane wave at nose-on incidence from an ogive. (Author)
