The electromagnetic field can be analyzed using Maxwell's equations but the electric or magnetic field must be known to completely analyze the unknown field. The wave equation solution will begin with the Cartesian coordinate system but will be extended to cylindrical and spherical coordinate systems. The derivation of Maxwell's differential or When an electromagnetic wave propagates through a condensed medium, its properties are modified by the coupling of the electromagnetic wave to the elementary excitations of the medium. The coupled excitation is frequently referred to as a polariton and consists of a photon coupled to a plasmon, optical phonon, magnon, etc. An electromagnetic
