Analysis of EMP Response of Structures Using Frequency Domain Electromagnetic Interaction Codes

Abstract

This 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 the efficient use of computer time.
