Seiler, Jr, L W

An electromagnetic pulse (EMP) model is developed which allows a quick computation of the time development of the electric fields generated by a high altitude nuclear burst. The model is based on the Karzas-Latter high frequency approximation for high altitude EMP, which describes fields generated by Compton electrons interacting with the earth's magnetic field. The proper choice of a gamma time output function, which can be integrated in closed form, and a small angle approximation, made in the expressions for the Compton currents and air conductivity, eliminate the time consuming numerical integrations usually necessary in EMP models to compute the Compton currents and air conductivity. This results in a considerable savings in computation time. The model is presented in a manner which is simple to use but still allows the variation of the major theoretical parameters in the problem.
