Claim:
1. A transparent capacitive powering system comprising: a pair of receiver electrodes connected to a load through an inductor wherein the inductor is coupled in series with the load; a pair of coupling plates configured to receive a power signal generated by a driver; a transparent infrastructure having at least a first layer of a non-conductive transparent material and a second layer of a conductive transparent material coupled to each other, wherein the second layer is arranged to form a pair of transmitter electrodes, wherein the pair of coupling plates are decoupled from the second layer, thereby forming a first capacitive impedance between the pair of transmitter electrodes and the pair of coupling plates, wherein the pair of receiver electrodes are decoupled from the second layer, thereby forming a second capacitive impedance between the pair of transmitter electrodes and the pair of receiver electrodes, wherein the power signal is wirelessly transferred from the pair of coupling plates to the pair of transmitter electrodes and from the pair of transmitter electrodes to the pair of receiver electrodes to power the load when a frequency of the power signal substantially matches a series-resonance frequency of the inductor, the first capacitive impedance, and the second capacitive impedance.
