Abstract

Electromagnetic induction (EMI) systems often use separate transmit and receive coils. In these systems, it is desirable for the transmit and receive coils to have minimal mutual coupling and a maximum eld product, thus maximizing the detection depth. We demonstrate that a pair of spiral coils can be optimized to achieve these desired properties. A mathematical representation is chosen for the coils that allows the coil pair to be optimized using an iterative convex method, which, due to its convexity, is very fast. We then present results showing both a pair of nonuniformly-wound, single-sided spiral coils and a pair of nonuniformly-wound, double-sided, spiral coils created with this optimization.
