可穿透腔体外有裂缝的正散射问题
The Direct Scattering Problem for a Penetrable Cavity and a Crack
摘要
Abstract
In this paper, by using a time harmonic point source as the incident wave, we consider the scattering problem of a mixed scatterer composed of a penetrable cavity and an external impenetrable crack.The problem comes down to solving the Helmholtz equation with certain boundary conditions.By using the boundary integral equation method, based on the potential theory and Fredholm theorem, we prove that the scattering problem has a unique solution.关键词
