ELECTRODYNAMICS OF TEM RADIATION NORMALLY INCIDENT UPON A SEMIINFINITE 2-LAYERED METAL IN THE GOOD-CONDUCTOR APPROXIMATION

Analytic expressions for power dissipated in each of both metals for t he case of a steady-state transverse electromagnetic (TEM) plane wave normally incident upon an arbitrary semi-infinite bimetallic bulk stru cture in the good-conductor approximation are obtained. Assuming the m aterial parameters are linear in the TEM amplitude, expressions for po wer dissipation in each metal, as well as the surface impedance of the bimetallic structure are in arbitrarily good agreement with results o btained from a transmission-line analog and Poynting's theorem. The po wer dissipation for structures with a constant thickness of metal 1 ar e plotted as a function of the conductivity of metal 1 and are superim posed upon the general phase space domain to self-consistently illustr ate the applicability of the continuum approximation used.
