Formulation of electromagnetic pulse external interaction above a lossy earth
Abstract
Two separate but related efforts are described in this report. The first and more significant effort is a demonstration of the capability of the patch zoning method for numerically solving the magnetic field integral equation (MFIE). This is accomplished by comparing experimental data with numerical computations of the current density induced on metallic structures. The secondary effort is a derivation of the electric field integrodifferential equation (EFIDE) and the MFIE for electromagnetic pulse external interaction with perfectly conducting bodies above a finitely conducting halfspace. The relationship between the two efforts is that the equations are represented in such a manner that the computational results, which are compared with experimental data, are readily seen to correspond to the numerical treatment of special cases of the MFIE finitely conducting ground equations.
