N.A.T. development has developed a three part approach to achieve shielding in new and used equipment that provides superior economics, as well as improved physical properties. The goals and objectives of the project follow. 1) optimization of the rheological/application properties of 'state of the science' conductive coatings. These systems combine the EMP conductive efficiencies of silver and/or gold with glass spheres and/or hollow glass beads to obtain a coated material with EMP conductive properties equal to silver and/or gold filled matrix systems at approximately one-seventh the loading, with superior performance, density and volume concentrations to achieve EMP resistant coatings technology that can be cost effectively applied directly to new and/or used equipment, facilities, concrete and walls. 2) incorporation and stabilization of these materials to achieve EMP resistant coatings that can be applied directly to fabric or other suitable substrate, to create, a portable EMP shroud (as in SBIR '85 #93 army), a EMP wallcovering (SBIR '86 #5 DNA) or EMP "free" zone with > 90db attenuation. 3) the last project effort is to formally evaluate and report on comparative current 'science' on low cost electromagnetic shielding systems. Physical properties of the evaluated conductive systems shall criteria 'quality shielding' (>>0 db-attenuation [attainable by (silver/silver-fillers] see testing/contacts). This will set priority and optimized the data base effectiveness of the evaluation.
