Abstract

Irregular-shaped wiring structures are usually encountered in practical applications. In this work, a wiring structure encompassing a loop is modeled geometrically by resorting to a 3D cylindrical helix. To predict the disturbances induced by an incident electromagnetic field at the terminals of such a nonuniform structure, a simplified numerical solution based on transmission-line (TL) theory is developed. To this end, the structure is discretized in segments and the Agrawal TL model is formulated by accounting for the actual orientation of each wire segment with respect to the incident electric field vector. Full-wave simulations of the current induced in the terminations of the wiring structure under analysis are used to validate the accuracy of the proposed numerical TL-based method as well as its computational effectiveness.
