阻尼边界条件障碍在分层介质中声波散射问题的数值算法
On the numerical solution of the acoustic scattering problem for an impedance boundary condition obstacle buried in different dielectric cylinders
摘要
Abstract
T he problem of impedance boundary condition obstacle buried in different dielectric cylinders was discussed .By using the jump relationship and combined single and double-layer potentials theory , this problem was turned into boundary integral equations ,then it transformed into solving linear system of equations by applying the Nyström method .Finally ,for different scattering obstacles ,the numerical examples were given to test the validity of the method .关键词
