Abstract
According to one embodiment, an electromagnetic wave attenuator includes a plurality of magnetic layers, and a plurality of nonmagnetic layers. The plurality of nonmagnetic layers is conductive. A direction from one of the plurality of magnetic layers toward an other one of the plurality of magnetic layers is aligned with a first direction. One of the plurality of nonmagnetic layers is between the one of the plurality of magnetic layers and the other one of the plurality of magnetic layers. A first thickness along the first direction of the one of the plurality of magnetic layers is not less than ½ times a second thickness along the first direction of the one of the plurality of nonmagnetic layers.
