Abstract
In an embodiment, a method for wirelessly transferring power through a low-e window includes: causing a first current to flow through a transmitter coil disposed in a first outer surface of the low-e window, the first current having a first frequency; inducing, with the first current, a second current to flow through a receiver coil disposed in a second outer surface of the low-e window, the low-e window having a metal or metal oxide layer having a first thickness; generating a voltage based on the second current; and powering an electronic device coupled to the receiver coil with the generated voltage, where the first frequency is associated with a first skin depth of the metal or metal oxide layer, and where the first skin depth is larger than the first thickness.
