Abstract:	本研究利用導電損失原理將不繡鋼纖維，5%、10%、20%、100%不銹鋼混紡紗編織為平紋針織結構作為電磁波吸收體之護幕層。因為針織物具有特殊之結構性質，能使護幕表面達到有效之電磁波干涉、繞射、多重反射效果。本實驗控制導電纖維種類、材料成分、針織物針圈大小及針織護幕測量角度等因素，製作1/4λ型電磁波吸收體，匹配出最佳組合之電磁波吸收體，對電磁波衰減效果高且電磁波吸收頻寬具優異之特性。 In this paper, the screen layers of electromagnetic-wave absorption are made by plain inlaid knitted structure blended with 5%, 10%, 20% and 100% stainless steel yarn. Because of the special structure on knitted fabric, it can make the electromagnetic-wave interference, diffraction and multi-reflections possible on the surface screen. This research was to control the kind of conductive fiber, the component of material, the structure of needle loop, and the measured angle of screen in order to satisfy 1/4λ electromagnetic-wave absorption. Moreover, this study was found to be effective in having wide absorption band gap and great attenuation ratio of electromagnetic-wave.
