本研究將螺旋孔徑0.8cm及l.0cm之螺旋狀銅線製作成直立式複合型板材進行電磁波吸收效益之測試，藉由不同線圈間距以及不同螺旋孔徑及改變板材厚度來進行電磁波吸收效益之測試。由實驗得知，螺旋孔徑0.8cm之直立式板材比螺旋孔徑l.0cm之直立式板材吸收值來的佳，螺旋孔徑0.8cm在線圈間距0.4cm，板材厚度0.5cm時有最高電磁波吸收值，其值可達25dB。
This research the spiral-shaped copper wire manufactures spiral aperture 0.8cm and 1.0cm the erectness type multi-skill plate to carry on test of the electromagnetic wave absorption benefit, carries on test of the electromagnetic wave absorption benefit because of the different coil spacing as well as the different spiral aperture. Knew by the experiment that erectness of type plate the spiral aperture 0.8cm the good which comes erectness of type plate absorption value compared to the spiral aperture 1.0cm, spiral aperture 0.8cm when coil spacing 0.4cm has the highest electromagnetic wave absorption value, its value may reach 25dB.
