Abstract :
A numerical technique for solving the high frequency approximation electromagnetic pulse (EMP) equations is presented. The Lorentz model of the secondary electron current is used, thereby achieving a result valid for a burst above the ground and observer at any altitude. Comparisons of the results of this technique and those techniques which assume an ohmic secondary electron current are made, and it is found that they are identical for observations below 40 km but differ markedly above 80 km.
