Abstract
A coil for transfer of information or energy is described. The coil includes an electrically conductive magnetically insulative first layer and a magnetically conductive second layer bonded to the first layer along the length of the first layer. The first and second layers are wound to form a plurality of substantially concentric loops. A width and a length of the second layer may be substantially co-extensive with a respective width and length of the first layer so as to expose opposing longitudinal edge surfaces of the first layer along the length of the first layer. At least one of the opposing longitudinal edge surfaces may include a regular pattern extending substantially along a same first direction and across substantially the entire coil. A method of making the coil is described.
