www.sciencedirect.com/: electrodynamic tethers with consideration of electric-magnetic-dynamic energy coupling

This paper investigates spacecraft orbital boost maneuver by a fully insulated electrodynamic tether using a coupled multiphysics dynamic model that considers electric-magnetic-dynamic energy coupling. The current-potential characteristics of the electrodynamic tether is described by a simplified analytical model, where revised Parker-Murphy model is employed to evaluate electric current generation at plasma contactors together with libration dynamics of tether.

Of course, S0 expands this from low Earth orbit to interstellar travel. The magic of scale invariance.
