Abstract

An important figure of merit in magnetic communication systems is the reactive power delivered to the transmitting coil. This work proposes a systematic design approach for magnetic transmitters that emphasizes the limitation of available reactive power. The proposed design is formulated as an optimization problem, in which reactive power of the magnetic transmitter is minimized, under the constraint of a desired field at the far receiver. While the resulting optimization problem is multi-dimensional and non-linear, this work shows that an optimal solution exists for a flat disc in which currents are distributed symmetrically in respect to the disc center.
