Conclusion

The scientific approach adopted in the article essentially concerned one-dimensional propagation and the use of results frequently borrowed from transmission line theory. The question is whether there are other, more complex material configurations where the parallelism of reasoning with line theory can be pursued.

Let's not forget that one of the major restrictions of this theory comes from the approximation of electromagnetic transverse wave propagation (TEM), the physical context of which was discussed in the conclusion of the first paragraph of [D 1 322] . In particular,...
