An Inverse Mixed Impedance Scattering Problem in a Chiral Medium

An inverse scattering problem of time-harmonic chiral electromagnetic waves for a buried partially coated object was studied. The embedded in piecewise isotropic homogeneous background material. On the boundary object, total field satisfied perfect conductor and impedance conditions. A modified linear sampling method, which originated from reciprocity gap functional, employed reconstruction shape without requiring any priori knowledge material properties object. Furthermore, characterization object’s surface determined.
