Abstract--Wireless power technology offers the promise of
cutting the last cord, allowing users to seamlessly recharge mobile
devices as easily as data is transmitted through the air. Initial
work on the use of magnetically coupled resonators for this
purpose has shown promising results. We present new analysis
that yields critical insight into design of practical systems,
including the introduction of key figures of merit that can be
used to compare systems with vastly different geometries and
operating conditions. A circuit model is presented along with a
derivation of key system concepts such as frequency splitting, the
maximum operating distance (critical coupling), and the behavior
of the system as it becomes under-coupled. This theoretical
