Abstract
The report concerns the use of frequency domain computer codes such as the Numerical Electromagnetic Code (NEC) for computing the time domain Electromagnetic Pulse (EMP) response of structures such as antennas, aircraft or communication shelters. The proper representation of the EMP excitation and the selection of a number of appropriate frequencies to obtain a correct time domain EMP response are studied. The effects of adapting the modelling of the problem for different frequency ranges is discussed. Guidelines are given for obtaining a correct time domain response with efficient use of computer time.
