Progress accomplished toward predicting the electromagnetic pulse produced by a nuclear weapon is reported. This work consists of the following 1 a real-time finite difference code, using prolate spheroidal coordinates, which will predict the electromagnetic fields produced by certain current distributions with azimuthal symmetry, 2 a retarded time code which in other respects is similar to the one listed above, 3 a one-dimensional finite difference code for predicting the fields of a current distribution with spherical symmetry, 4 a computer code which numerically evaluates the exact solution of Maxwells equations for the case of spherical symmetry, 5 a numerical solution of the diffusion approximation of Maxwells equations in a region which includes an infinitely conducting earth, 6 work toward obtaining a Greens function for Maxwells equations with some restrictions on the time dependence of the conductivity, and 7 a numerical integration code that combines the results of two previously existing Monte Carlo neutron and gamma ray transport codes in order to obtain currents produced by gamma ray sources in the ground.
