Abstract:	本研究主要利用不飽和聚酯樹酯作為基材，將錐形螺旋銅線依正、反、交錯排列，置入不飽和聚酯樹脂當中，製成複合材料之電磁波吸收體，最後導入電流測量其吸收效果。銅線圈數分別為5、15、25圈，問距為lcm、1.5cm、2cm，各別探討其電磁波吸收效果，當圈數為25園時，間距為lcm，圈數25圈，導入電流20V其最高吸收值為44.ldB。隨著錐形螺旋銅線圈數的上升，能適時使電磁波入射波在錐形螺旋銅線間形成干涉共振，能有效的將電磁波轉換成熱能散失。 The main advantage of this study of unsaturated polyester resin as base material, the conical spiral copper positive and negative, staggered, in unsaturated polyester resin, made from a composite of electromagnetic wave absorber, last import current measurement of the absorption effect. Copper Coils respectively 5, 15, 25, spacing of 1 and 2, 1.5 cm,, severally and explore its electromagnetic wave absorption effect, when the number of turns is 25 laps, the spacing is 1 and the number of turns 25 laps, importing current 20V its maximum absorption value 44.1dB. As the number of conical spiral copper coils, timely the rise of the electromagnetic wave incident wave in between conical spiral copper, interference resonance can be converted into thermal energy loss of electromagnetic waves.
