Description
Summary:This paper deals with the susceptibility of wiring harness of a complex system to radiated electromagnetic fields. In particular, the possibility of deducing information on the interfering field via experimental measurements is explored. The experimental procedure is intended to provide the inputs required for the definition of a new class of radiated susceptibility (RS) test procedures. It is shown that the field scattered from the wiring may substantially affect measurement accuracy of the incident field. The different roles played by the vertical and horizontal components of the scattered field are evidenced via simplified models. Practical guidelines are provided for the sensor positioning, based on statistical estimates of the measurement error. Reliability of field measurements for RS assessment is investigated by employing a numerical electromagnetic solver as a virtual measurement system.
