Abstract:	本研究係利用不同含量5%、10%、20%、100%的不鏽鋼混紡炒為材料，以改變針織內部的結構為變因，編織成平紋針織結構作為單層電磁波吸收體的護幕層，再以阻抗來匹配成多層的電磁波吸收體，來測試各電磁波吸收體對電磁波的吸收效果與頻寬率加以分析並比較。利用平紋針織物結構蓬鬆，設計電磁波吸收體能符合厚度薄、質量輕，又具有良好的電磁波吸收效果與寬頻化之優勢，本研究結果電磁波最佳吸收效果能達25-30dB。 The main purpose of this study is analyzing and comparing the absorbance and frequency range of different electromagnetic wave absorbers. The experimental variable were stainless steel yarn with different inner structure via different composition, say 5%, 10%, 20%, 100%, knitting to form a plain weave knitted structure as a screen of monolayer electromagnetic absorbers. The advantages of plain weave knitting to form a thin and light electro-magnetic wave absorber were the fluffy structure. The results showed the absorbing effect were 25-30dB.
