Inversion of two-dimensional conductivity structures

Abstract This review shows that the inversion of two-dimensional structures is still an almost uninvestigated area. Only for very restricted anomalous domains exact methods exist: (a) undulated interface between perfect conductor and insulator; (b) thin non-uniform sheet. So far, real conductors must be inverted by linearization. A method for the computation of the pertinent kernels is described and the well-developed method of generalized matrix inversion is applied in a preliminary study both to artificial and real data.
