Load response of terminated transmission lines exposed to external electromagnetic fields

Plane-wave excitation fields are by far the most commonly used in field-to-wire coupling computations. Nevertheless, such excitations are not always adequate for the immunity assessment of wire-type structures operating in the contemporary man-made environment. To reinforce this conjecture, this study examines two-wire transmission lines excited by common non-uniform fields. Numerical results for the induced load voltages show notable deviations from those obtained under the assumption of plane-wave incidence.
