Thin Sheet Modelling of Subsurface and Deep Inhomogeneities

What is it about?

The paper presents a method which can be used to calculate electromagnetic fields excited in non-uniform media by fields of either natural origin or controlled sources. The model under consideration consists of several inhomogeneous thin sheets embedded in an otherwise laterally uniform section. Maxwell's equations are reduced to a system of integral equations with a compressive kernel, which can always be effective1y solved using the iterative-dissipative method. Some details of a numerical realization are given together with an example of modeling.

Why is it important?

Besides presenting the theoretic foundations of the approach the paper gives an example of modeling the electromagnetic fields induced in a real region with almost orthogonal directions of the overwhelming features of the surface and deep heterogeneous layers.
