EMF shield
An EMF shield is disclosed. The EMF shield includes a scattering layer and a reflective layer having an exterior surface and an interior surface opposite the exterior surface. The scattering layer includes a metal coating disposed at the exterior surface. The reflective layer includes a first side and a second side opposite the first side, the first side of the reflective layer being coupled to the interior surface of the scattering layer, wherein the reflective layer comprises a dielectric material. The metal coating includes an adhesive coating for coupling to an electronic device. The EMF shield is configured to scatter and reflect the EMF signal. After the EMF signal is initially scattered by the metal coating, the reflective layer causes the EMF signal to reflect.
