Abstract

Electromagnetic induction (EMI) systems often employ separate transmit and receive coils that are placed in close proximity to one another. This placement is desirable for packaging reasons, but it makes achieving minimal mutual coupling between the two coils difficult. An iterative-convex optimization procedure that allows coils to be designed for both minimum mutual coupling and maximum on-axis sensitivity is demonstrated, and then this procedure is used to create a pair of double-sided, non-uniformly wound spiral coils, which improve upon previous coils by making the transmit coil resistance uniform. The effects of capacitive loading within the coils are explored, and results showing that the coils perform as expected at low frequency are presented.
