Generalized Snell’s Law and Maxwell Equations

Abstract. This paper examines the Maxwell system of electrodynamics within the framework of distributions. A primary objective is to establish general boundary conditions for fields at interfaces when the charge and current densities are measures localized on the interface. From this analysis, the paper presents a derivation of the generalized Snell’s law, along with formulas for the amplitudes of the reflected and transmitted waves in terms of the incident amplitude.
