Wireless Power Transfer Using Open-Wire Transmission Line Coupling
Abstract
This dissertation presents and develops a novel method of wireless power transfer that relies on electromagnetic coupling from open-wire transmission lines instead of traditional methods. Wireless power transfer techniques are being rapidly pursued in research currently due to the potential utility of powering devices over the air instead of with direct electrical connections. Uses for such techniques include an array of applications from consumer electronics, to medical devices, to cars and UAVs. While conventional wireless power transfer techniques exist, it is shown here that open-wire transmission line methods present distinct advantages for certain applications. In particular, wireless power transfer using Goubau and twin-lead line architectures will be conceptualized and investigated in terms of their theory, design, and efficiency performance. Further, a circuit model theory will be developed in this work to provide a generalized formulation for open-wire-line wireless power transfer analysis. Additionally, receiver design techniques will be outlined and geometries based on metamaterial principles will be pursued in order to achieve receiver miniaturization and access the applications this affords.
