Abstract:

A core includes a first layer, a second layer, and a third layer. The first layer has a first surface, a second surface, and a first recessed pattern extending from the second surface of the first layer toward the first surface of the first layer. The second layer has a third surface, a fourth surface, a second recessed pattern extending from the third surface of the second layer toward the fourth surface of the second layer, and a third recessed pattern extending from the fourth surface of the second layer toward the third surface of the second layer. The third layer has a fifth surface, a sixth surface, and a fourth recessed pattern extending from the fifth surface of the third layer toward the sixth surface of the third layer. The second layer is disposed between the first and third layers such that the second surface of the first layer faces the third surface of the second layer and the fourth surface of the second layer faces the fifth surface of the third layer. The first and second recessed patterns correspond to one another and are configured to receive a coil. The first, second, and third layers have non-uniform magnetic permeabilities.
