Abstract

"An investigation to determine the applicability of statistical modeling techniques to shielding effectiveness estimation of complex, irregular structures is proposed. In particular, the ability to extrapolate existing shielding effectiveness data tosimilar structures (similitude) is of interest. Accuracy, efficiency, validation and usefulness are the evaluation criteria used to establish applicability.Using statistical techniques, it has already been demonstrated that the shielding effectiveness of electrically large, metallic walled irregular structures can be uniquely defined. Techniques for accurately measuring and estimating the shieldingeffectiveness exist. Validation, measurement and computational costs are minimal and applications of similitude are straightforward. The definition is also compatible with vulnerability assessment requirements so it is also useful. The proposed effort willinvestigate the applicability of these techniques and/or modification of these techniques to structures with different wall materials and/or smaller electrical sizes. Wall materials of interest include dielectric and combinations of dielectric/metal(re-enforced concrete). Accurate, cost effective techniques for estimating the shielding effectiveness of a wide class of structures would provide lower cost solutions for protecting critical electronic systems. This approach would provide the tools necessary for identifying themost vulnerable compone
