The purpose of this Note is to outline and numerically illustrate the essential details of a fully three-dimensional method of calculating the radiated electromagnetic signal from magnetic deflections of a distribution of Compton electrons produced in the upper atmosphere by prompt gamma radiation from a high-altitude nuclear detonation. The three-dimensional method evaluates the radiation fields (at a given time) from individual electrons. It uses Lienard-Wiechert potentials and sums the fields from all the spatially distributed electrons which contribute to the observer field at a given time. Section II gives details of the principal steps of the electron field summation methods of EMP calculation. For simplicity in presenting the method, vertical geometry and a magnetic field perpendicular to the burst/observer path are used, and numerical values are illustrated for all steps in the development of the method.
