Solution of Maxwell´s equations in three space dimensions and time by the t.l.m. method of numerical analysis

The paper shows how a general 3-dimensional medium may be represented by a simple model made up of generalised 2-dimensional nodes. It is then shown how this model may be used for the numerical solution of electric and magnetic vector fields within the medium, without any mathematical formulation of the problem. Results for the resonant frequencies and power decay times of some cavities partially filled with dielectric are given using this method. There has been an excellent agreement in all cases where comparisons could be made.
