Abstract
Method and apparatus for eliminating mutual inductance effects in resonant coil assemblies in which a plurality of coils are situated in sufficiently close proximity to create small mutual inductances between the coils. The method comprises evaluating the mutual inductances using a T, star or other transformation of the relevant parts of the circuit, thereby isolating the mutual inductances in such a way that series capacitances may be introduced to tune out the mutual inductances at a common frequency, reducing the coil array to a synchronously tuned circuit.
