Shielding of a communication data link against EMP threat
Abstract
A method is presented in this paper for determining the shielding effectiveness of metal shields to protect data links from EMP threats. For this purpose the EMP is expressed in double exponential analytical model. The cylindrical shielding structure is approximated by tubes made of steel, copper and aluminum separately and is considered for working out mathematically the minimum thickness of tubular shields necessary for optimum shielding. The results of analysis are shown graphically. Computations are carried out using Fast Fourier Transform (FFT) technique to get the EMP spectrum. Field coupling, into a metal tube, is evaluated using classical coupling equations.
