Development and testing of DAVID: A closein EMP coupling code for arbitrarily shaped objects
Abstract
This report describes the development and testing of a 3D, finite difference computer code used to estimate the currents and voltages induced on an arbitrarily shaped object when illuminated by a plane wave gamma source. The application of the code is for performing calculations to aid in the prediction of closein EMP effects on systems. Included is a description of the way the physics of the problem is handled by the code, the methods used to obtain numerical solutions, the results of comparison tests and conclusions and recommendations.
