1. An array of electrical resonators for wirelessly transferring power to a receiver, each of the electrical resonators comprising:
an inductor coil comprising at least one turn comprising:
an outer turn defining an outer coil perimeter; and
at least one capacitor connected to the inductor coil;
wherein the outer coil perimeter comprises:
four major edges, wherein each major edge is substantially linear and arranged on a different edge of a quadrilateral; and
four minor edges connecting the major edges;
the array comprising:
a first plurality of the electrical resonators arranged in a first layer; and
a second plurality of the electrical resonators arranged in a second layer on top of the first layer;
wherein the minor edge of each electrical resonator substantially abuts the minor edge of an adjacent electrical resonator in the same layer, and the first and second layer together define a quadrilateral array of the electrical resonators, with a center of each inductor coil in the first layer coincident with the center of a gap region between inductor coils in the second layer;
wherein the outer coil perimeter comprises an octagonal coil perimeter.
