A preliminary study of the electromagnetic shielding effectiveness (EMSE) using metal coating films and a vacuum evaporation depositon technique with the woven fabrics made of metal/PET filaments is presented. Using coaxial transmission equipment, the EMSE of these films and fabrics was measured in the frequency range 2250-2650 MHz. The experimental results indicate that different coating materials have different EMSE, with a thicker coating film having a higher EMSE, with a thicker coating film having a higher EMSE. In addition, a woven fabric with lower aperture ratio made from metal/polyethylene terephthalate (PET) filaments has higher EMSE, and the electromagnetic shielding of polarized electromagnetic waves possesses orientation effects. The paper provides theoretical guidance for designing flexible electromagnetic shielding products.
