Abstract:

Investigations are being conducted to determine the effect of electromagnetic radiation upon electroexplosive components. It is indicated that the best solution would be to incorporate an RF attenuator a broad-band absorber within the item to be protected, plugging the leak which exists in the natural shield provided by the metal case in which most electroexplosive components are contained. Included in the scope of the work are the following 1 Fundamental studies of the important characteristics of RF attenuator materials 2 Practical optimization of materials, including improvement of voltage breakdown characteristics, dc resistance, mechanical strength, as well as improved attenuation 3 Evaluation of materials such as ferrites to determine if a material superior to the carbonyl iron can be found and 4 Study of the effects of configuration and geometry upon attenuation.
