General solutions of Maxwell's equations for signals in a lossy medium. I. Electric and magnetic field strengths due to electric exponential ramp function excitation

摘要

Modification of Maxwell's equations to obtain general solutions for a lossy medium is reviewed. It is done by adding an extra term, referred to as the fictitious magnetic charge density. The solutions, which are in integral form, are solved numerically by computer for an exponential ramp function excitation. Computer plots for the electric and magnetic field strengths as functions of time at different locations in a lossy transmission medium are presented.
