Abstract : The use of scalar potentials in the solution of electromagnetic boundary value problems is described. Explicit solutions of fields at a dielectric interface and at a perfect conductor are derived in terms of the solutions to the wave equation that obey Dirichlet and Neumann boundary conditions. Application of a finiteness condition and a radiation condition are discussed. As an example of the approach, the Fresnel equations are derived. The scaler potentials used here are compared with the Debye potentials and the coupled azimuthal potentials, which have been used for similar applications.
