Modified Agrawal Field-to-Transmission Line Method Based on Equivalent Total Tangential Electric Field Source Terms

This paper presents an application of a modified field-to-transmission-line-model inspired from Agrawal's model. In this model the field applied as a source term includes the tangential incident electric field as well as surrounding tangential scattered electric fields due to the current induced on the transmission-line. This weak domain decomposition approach allows one to calculate currents accounting for the reaction of those currents on the EM incident fields. The theoretical development is made on the basis of a two-wire transmission line; it is then extended to any transmission-line geometry. A numerical validation is made on several configurations of excitations of single wire transmission line networks. Particularly the results show that this model is able to predict the EM radiation of the cable. The paper concludes on future possible applications of this modified field-to-transmission-line approach in real applications of cable bundles in 3D structures of industrial complexity.
