Abstract:
A system for wirelessly projecting power to wirelessly power microelectronic devices, the system comprising:an array of current loops that are disposed adjacent to one another to define a surface and to define an in-phase virtual current loop at a periphery of the surface that produces a same direction, in-phase virtual current while current in adjacent portions of adjacent current loops flows in opposite directions, to wirelessly project power orthogonal to the surface to power microelectronic devices that are spaced apart from, and orthogonal to, the surface; wherein the array of current loops comprises an array of at least ten wedge-shaped current loops each having an outer portion and a pair of sides. the at least ten wedge-shaped current loops being disposed adjacent to one another to define a surface such that currents in the outer portions are in-phase and current in adjacent sides of adjacent current loops are out-of-phase.
