2D modeling of bulk current injection probe and validation with measurements

Abstract

Electronic Equipment designed to be loaded onto an aircraft must be certified in accordance with established EMC standards. This paper is focused on section 20 of RTCA-DO160 which refers to conducted susceptibility in aeronautics. Since equipment can succeed or not in qualification test, aim is to be able to predict these levels of disturbance for limiting costs and time design. Moreover, aircraft manufacturers are mostly looking for precise answers about the sensitivity and reproducibility of these tests. In this sense, a 2D model of probe coupling to wires is developed in this work.
