TLDR
In this paper, a generalization of the electromagnetic topology approach to nonuniform transmission lines is presented, and a comparison between theoretical and experimental results shows the validity and the interest of this approach.Abstract:
The electromagnetic topology approach is often used to calculate the current or voltage that can appear on a transmission line network illuminated by a disturbing wave. However the lines are supposed to be parallel to a ground plane and, furthermore, the model has often been applied on canonical cases. A generalization of this formalism to treat nonuniform transmission lines is presented. Moreover, by treating a wiring installed inside a Transall airplane mockup, a comparison between theoretical and experimental results shows the validity and the interest of this approach. >read more

Electromagnetic Topology: An Additional Interaction Sequence Diagram for Transmission Line Network Analysis
TL;DR: A new interaction sequence diagram called the coupling order graph (COG), which is able to quantify further approximations in complex situations, is presented and it is shown that approximate evaluations can be obtained from the subnetworks that are far simpler than the original one.
