Abstract
A low frequency electromagnetic field shielding panel having a first domain refined steel sheet with an easy direction parallel to a first axis and a second domain refined steel sheet substantially overlying the first sheet and having an easy direction generally orthogonal to the easy direction of the first sheet. The EMF shielding panels are interspersed between an EMF source and a critical volume rather than encapsulating the source or the critical volume.
