ABSTRACT:
An electromagnetic shielding material for absorbing electromagnetic energy has been found. The shielding material is flexible and has a thin conductive core with a composite ferrite material deposited around the core. The composite ferrite material is a mixture of ferrite powder and a binder for binding the powder. The conductive core may be formed in the shape of a flat sheet or an elongated textile shape. The binder may be a high molecular compound like plastic. When the core is in a textile shape, the textile covered with the composite ferrite material is woven into a cloth which is sufficiently flexible to form around any desired shape.
