Abstract: A shielding medium using a multi-layered construction for protection of an object such as the human body, with each layer containing a plurality of geometrically shaped objects, that appears to the EMFs as a continuous, solid plane, but retains open spaces around the objects for ambient air to circulate. As a result of this construction, the unique shielding medium affords excellent protection against both the electric and magnetic field components of EMFs without sacrificing the comfort of the user (or heat dissipation of the source).
