<p>This dissertation presents and develops a novel method of wireless power transfer
that relies on electromagnetic coupling from open-wire transmission lines instead of tra-
ditional methods. Wireless power transfer techniques are being rapidly pursued in re-
search 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 ap-
plications from consumer electronics, to medical devices, to cars and UAVs. While con-
ventional wireless power transfer techniques exist, it is shown here that open-wire trans-
mission line methods present distinct advantages for certain applications. In particular,
wireless power transfer using Goubau and twin-lead line architectures will be conceptual-
ized and investigated in terms of their theory, design, and efficiency performance. Fur-
ther, a circuit model theory will be developed in this work to provide a generalized for-
mulation for open-wire-line wireless power transfer analysis. Additionally, receiver de-
sign techniques will be outlined and geometries based on metamaterial principles will be
pursued in order to achieve receiver miniaturization and access the applications this af-
fords.
