Systems and methods are described that increase pad efficiency and robustness. These systems and methods balance magnetic flux density in ferrite strips in a WEVC pad to reduce heat produced in high-flux areas of the ferrite strips. Aspects include controlled spacing between ferrite strips of a WEVC pad and intentional gaps located within high-flux areas in the strips. The sizes of the intentional gaps are determined in relation to the size of the spacing between the strips. In addition, ribs are disposed between the strips and connected to a backplate to provide structural rigidity and robustness to the pad.
