本文给出了一种由已知入射平面波对应于固定频率的时谐电场的远场分布来确定部分涂覆各向异性介质表面电导率的基本上确界的变分方法。假设已经确定了散射体的形状(例如，通过求解远场方程和使用线性采样方法)。给出了表面电导率为常数的标量情形的数值算例。
A variational method is given for determining the essential supremum of the surface conductivity of a partially coated anisotropic dielectric medium from a knowledge of the far field pattern of the time-harmonic electric field at fixed frequency corresponding to an incident plane wave. It is assumed that the shape of the scatterer has been determined (e.g., by solving the far field equation and using the linear sampling method). Numerical examples are given for the scalar case with constant surface conductivity.
