A Novel Segmentation Approach for Modeling of Radiated Emission and Immunity Test Setups

A novel procedure is developed to simulate radiated emission (RE) and immunity scenarios using a common approach for electronic control unit with complex wiring harness and terminations. This is possible by applying Huygens principle and Reciprocity theorem to the problem. A segmented approach is proposed to split the device under test into multiple segments, which converts the radiation problem to circuit simulation, in addition to reducing the requirement of computing resources. The proposed method is validated using measurements and also full-wave three-dimensional simulations for both RE and immunity test setups.
