Abstract In order to get the power frequency electric and magnetic shielding effectiveness of the composite materials, the experiment test methods are proposed respectively based on shielding enclosure method. By analyzing the experiment results when adjusting the test scheme, the experiment method is improved. The distributions of the electric field inside and outside of the shielding enclosure are obtained through the experiment. The experiment results can be used to determine the position of the electronic devices under protect in the shielding enclosure and guide the design of electromagnetic shielding enclosures.
