Integral equations that give the electromagnetic response of a thin disk situated beneath an inhomogeneous conductive overburden are derived, and expressions for the electric fields in the overburden and on the disk are given. The equations obtained can be used to estimate unknown parameters such as, the conductance and the depth of burial of the disk, as well as the thickness of the overburden. The estimation of the above parameters is important in the identification of subsurface structures. An inversion procedure is outlined whereby the optimal values for these parameters is obtained by an iterative technique.
