Capacitative Coupling (Capacitative Power Transfer): HV AC Electric Fields to Field Equipment

I would like to understand the Physics, Mathematics, Electronics, Electrical Engineering, and Circuit Design that must be applied to the problem of harvesting power from HV AC Electric Fields. I have a BS in Physics, but my Mathematical, EE/Electronics, and Analog Circuit knowledge, skills, and capabilities are not sufficient to permit me to perform calculations (using large parallel-plate capacitors, for example) that accurately estimate the AC Watts that could be harvested or coupled. I need someone with a very strong Physics background, solid mathematical capabilities (including SW such as MatLab, MathCAD, etc.), and solid Analog AC/DC Electronics (EE; Circuit Design) abilities to lay out, and then perform, the calculations necessary to make very accurate estimates.
