Abstract: This paper presents a simple methodology to measure the shielding quality in coaxial cables and connectors through the Shielding Effectiveness (SE) parameter at high frequencies. The discovery of complications as soon as possible is of paramount importance in order to avoid unpredicted costs in advanced phases of the project. This proposal describes an SE measurement setup using standard Electromagnetic Compatibility instrumentation such as electric field probe, signal generator, and power meter in a semi-anechoic shielded chamber and comparing physical measurement with computational simulations. A virtual model has been created based upon the physical coaxial cable, respecting dimensions and materials characteristics. The agreement between measurements and simulations is good in the considered frequency range 240 MHz to 3 GHz.
Keywords: Electric field, shielding effectiveness, coaxial cable, connectors
