Abstract
Properties of water-filled inductors are relevant for underwater wireless energy transfer. The influence of the relative permittivity and resistivity of the core material on the impedance of an inductor can be modeled with a lumped parameter circuit. The relative permittivity of the core material has influence on the turn-to-core capacitance of the inductor. The resistivity of the core material has a linear relation with the resistance of the turn-to-turn capacitance. With this model, the influence of the conductivity on the quality factor of an inductor can be predicted. This is a helpful tool to find the optimal frequency at which the quality factor is maximum.
