Influencing factors of shielding effectiveness test of electromagnetic shielding clothing
Journal of Industrial Textiles, 2022 There is no perfect method to test and evaluate electromagnetic shielding (EMS) clothing up to now. The main reason is that the influence laws of the emission source parameters and the test position on the shielding effectiveness (SE) of the EMS clothing has not been clarified.
