Investigating Voltage Excitation of the Darwin Model via the Prescription of Terminal Scalar Potentials

Developing simulation models for electromagnetic field problems often deals with approximations of the full set Maxwell’s equations, to obtain performant methods. This is also case so-called Darwin model, which has capability including resistive, inductive, and capacitive effects without need solving full-wave equations. However, an issue difficulty prescribing realistic excitations e.g., via a terminal voltage. In this article, straightforward prescription scalar potential on electric ports investigated Poynting’s theorem, outcome that it can be considered as physical voltage excitation up frequencies, where validity model itself lost.
