论文摘要
我们考虑了通过分段常数不均匀，可渗透和无限长的圆柱的直接散射问题的可溶性。我们使用边界值运算符和积分方程方法的属性证明了解决方案的存在和独特性。对于数值解决方案，我们采用搭配方法，并使用正交规则近似单数积分运算符。我们显示了近场和远场状态中内部和散射场的数值方案的收敛性。
We consider the solvability of the direct scattering problem of an obliquely incident time-harmonic electromagnetic wave by a piecewise constant inhomogeneous, penetrable and infinitely long cylinder. We prove the existence and uniqueness of the solution using properties of the boundary value operators and the integral equation method. For the numerical solution, we apply a collocation method and we approximate the singular integral operators using quadrature rules. We show convergence of the numerical scheme for the interior and the scattered fields both in the near- and far-field regime.
