The E-parallel polarization response of a two-dimensional heterogeneous layer modeled by two thin sheets

The flexibility of the thin-sheet technique for modeling two-dimensional structures is extended by analyzing the response to E-parallel to the strike of the anomaly polarization, also known as the transverse electric (TE) mode, when a heterogeneous Earth is modeled by two thin sheets over a horizontally stratified half-space. The electromagnetic fields induced by the heterogeneous layer when a uniform plane wave is normally incident on the Earth are expressed as integral equations, which are then evaluated using the method of moments. The resulting matrix equations are solved by the Gauss-Seidel method, and the magnetotelluric impedance is calculated
