Abstract
This invention relates to an apparatus for shielding electromagnetic radiation which includes a casing made primarily of electromagnetic shielding material and an electromagnetic wave suppressor member having high permeability and/or permittivity. A method for using this apparatus also is described. The suppressor member has a high dielectric loss and/or high magnetic loss at a location close to the place in the casing where electromagnetic waves are less shielded, thereby reducing leakage of undesirable electromagnetic waves from the casing.
