The Fresnel Equations that describe the transmitted and reflected waves at an interface between materials with different dielectric and/or magnetic properties are re-examined. A subtle error is discovered in the well known derivation of these formulas for lossy materials. Correcting this subtle error changes these formulas and results in replacing the(More)
Putting physical information into a numerical solution method can be used to produce fast solution methods. These methods can be extended to improve the stability of the solution procedure and answer. Iterative solution that requires a stable (well conditioned) formulation. However, truly large problems are also sensitive to stability issues. This paper(More)
