What is it about?
Digital connectivity via cables and connectors involves some degradation of the data being exchanged. In order for engineers to be able to design circuits and systems to recover the original data that would otherwise be lost in transmission, they require accurate models to first predict the degree and nature of the degradation: This article details a novel modelling approach that

Why is it important?
This article is important because it discusses several hitherto unacknowledged shortcomings in the standard textbook approach to transmission line modelling that affect accuracy in broadband high-frequency applications, while also providing practical solutions to these shortcomings.
Perspectives
This work is the culmination of a journey that began 30 years ago, and yet it has only been in the last six years or so that I have come to the realization that the high-frequency transmission line model that I had been actively using and developing for all that time did not align with textbook theory. Moreover, as it turns out it is not a difficult task to show that experimental measurements do not align with textbook theory either. I have found this discovery to be both surprising and thought-provoking, and I trust that my readers will too.
