本研究將不同粗細之螺旋狀銅線製作成複合材料之板材進行電磁波吸收效益之測試，藉由不同線圈數之螺旋狀銅線以及螺旋狀銅線排列密度來進行電磁波吸收效益之測試。由實驗研究得知，螺旋狀銅線粗細0.32mm、線圈數為1 5園、間距為1.5cm，其電磁波最佳吸收值為28.1dB。
There are plates of compound materia1s manufactured by helix copper wire with various thickness to be applied to the experiment on the electromagnetic wave absorption efficiency in the study. 80th the number and arrange density of the helix copper wire are varied for the experiment. The results show that the best absorption value of 28 .1 dB for electromagnetic wave can be obtained under the combination of helix copper wire size of twine 0.32mm, coil number 15 and layout spacing 1.5 cm.
