Validation of Shielding Effectiveness of Cables with Pigtails

Abstract

This report focuses on the validation of experimental da ta used to develop the field-to-wire coupling algorithm in the Intrasystem Electromagnetic Compatibility Analysis Program (IEMCAP). IEMCAP is a computer code used to assess the electromagnetic compatibility (EMC) of Air Force systems. The experimental data of interest was obtained by measuring, in a mode tuned reverberation chamber (MTRC), the shielding effectiveness (SE) of coaxial cables terminated in pigtails. The results of these measurements indicate that a coaxial cable terminated in pigtail has no shielding from electromagnetic interference (EMI). When repeating these measurements, it was found that coaxial cables terminated in pigtails can have a degree of SE. Due to the opposing results, the various characteristics of pigtails, such as length and construction, are investigated to determine which pigtail attributes critically reduce the SE of coaxial cables. From this investigation, the parameters that critically reduce the SE of coaxial cables are identified. Recommendations are then made regarding the field-to-wire coupling algorithm in IEMCAP and regarding follow-up investigations.
