Four variants of knitted fabrics with plain weft stitches were designed and manufactured from electrically conductive yarns with resistance of 490 ohms. The variants of the knitted fabrics differed significantly in structural parameters, including loop density – varying from 15 to 0.9 thousand loops and fabric cover from 64 to 33%. The barrier properties against reflected waves at frequencies from 2 to 7 GHz ranged from 10 to 64 dB. It has been proven that shielding effectiveness SE depends on stitch geometry and structural parameters of the knitted fabric. It is a good starting point for further research on the optimization of the performance of knitted barriers against electromagnetic waves.enDla wszystkich w zakresie dozwolonego użytkuFair use conditionelectromagnetic field EMFknitted electromagnetic wave shieldsshielding measurements and shielding effectiveness SEpole elektromagnetycznedziane ekrany fal elektromagnetycznychpomiary ekranowania i skuteczność ekranowaniaartykuł - konferencjaLicencja PŁLUT License10.34658/9788366741751.84
