Abstract :
Since the inception of conducted injection techniques to model radiated susceptibility/immunity coupling, considerable debate has ensued regarding its validity. This paper affirms the viewpoint of Szentkuti (1989), builds upon test results of Adams (1992) and Trout (1996), and discusses Perini´s theoretical observations (1993, 1995). Analytical and test results are presented which further demonstrate under what specific conditions conducted and radiated techniques can be correlated, and how the works of Adams, Trout, and Perini fit into the general problem of modeling field-to-wire coupling. At frequencies where transmission line and antenna effects are minimal, conducted immunity techniques provide excellent correlation with analytical and empirical predictions of radiated coupling. From a practical standpoint, conducted injection techniques provide realistic coupling at frequencies and amplitude levels that would be uneconomical to achieve with traditional radiated techniques
