The Van Veen Loop, Large Loop Antenna (LLA), or Loop Antenna System (LAS), provides rapid determination of the net magnetic dipole moment of compact devices, especially in the frequency range of 9 kHz to 30 MHz, with minimal post processing of measured data. The symmetric shielded loop structure inherently rejects electric field excitation to a large extent if the action of the current transformer is ideal. Here we consider the electric-field or common-mode response of an LLA with an imperfect current transformer. The impetus for this work is the application of the LLA to the characterization of Inductive Power Transfer (IPT) systems. It has been shown that such IPT systems exhibit, in addition to an intense magnetic dipole moment, an intense electric dipole moment. This is due primarily to the turn-to-turn voltage drop in inductive couplers.
