我们考虑了由涂覆无限长圆柱体散射的时间谐入射平面波的远场数据确定表面阻抗λ=λ(X)或表面电导率η=η(X)的问题。我们证明了λ和η是由远场数据唯一确定的，并提供了确定这些量的数值算法。
We consider the problem of determining either the surface impedance λ = λ(x) or surface conductivity η = η(x) from far field data corresponding to time-harmonic incident plane waves scattered by a coated infinite cylinder. We show that λ and η are uniquely determined from the far field data and provide a numerical algorithm for determining these quantities.
