This paper applies the collocation method to the modeling and simulation of scattering from a strip with the Dirichlet boundary condition on the upper interface and the Dirichlet and Neumann boundary conditions on the two subintervals along the lower interface. Green's theorem is used to reduce the mixed boundary value problem to the system of three coupled hypersingular and singular integral equations. The numerical results of the backscattering field characteristics are presented and compared with the high‐frequency approximations.

从带混合边界条件的带散射

本文将搭配方法应用于带上界面的Dirichlet边界条件和沿下界面的两个子区间的Dirichlet和Neumann边界条件的带状散射的建模和仿真。格林定理用于将混合边值问题简化为三个耦合的超奇异和奇异积分方程组。给出了反向散射场特性的数值结果，并将其与高频近似进行了比较。
