The research on shielding effectiveness measurement for electromagnetic shielding garments

A novel measurement system is established to analyze the performance of electromagnetic shielding garments in anechoic chamber. The human phantom body is filled with absorbing material instead of tissue fluid to prevent cavity effect and save the cost of manpower and money. An electric field probe is put in the abdominal cavity of human phantom body to receive the electromagnetic waves. Then electric field value of the abdominal cavity is measured with or without electromagnetic shielding garments on human phantom body. After comparing the mesured shielding effectiveness (SE) of different garments and the fabrics made into those different garments, the performance between garments and their corresponding fabrics are also discussed. It concludes that the design style is the determining factor to affect the SE value rather than metal fiber content. The research results can be applied to production and trade.
