Abstract

In the presence of a conductive slab, the mutual inductance of two coupled coils is no longer a real number but becomes a complex quantity whose modulus declines for increasing conductivity and thickness of the slab. In this work, we investigate the case when the two coils are entirely embedded in a conductive medium and derive new analytical formulae for the magnetic vector potential of a coil in a conductive space with dielectric gaps. Our results will have a significant impact on the design and optimisation of magnetoinductive waveguides for underground/underwater communications and embedded biomedical systems.
