© 2018 IEEE. The numerical dispersion and stability conditions for the full wave time domain propagator solution of Maxwell's equations are presented. The Propagator Method is a numerical integral operator technique for moving the electromagnetic field through a numerical space at successive time increments. A derivation of the numerical dispersion relation and stability condition in 1-, 2-, and 3-dimensions is presented. It is shown that the coefficients in the numerical equations in 2- and 3-D can be found based upon a dispersion and stability condition analysis.
