Abstract:	本研究固定螺旋結構2.5cm、3.5cm、4.5cm下改變其螺旋孔徑。3cm、0.4cm、0.5cm以不同排列密度1cm、2cm、3cm探討其電磁波吸收效益。並將其螺旋複合板材匹配不同直線複令板材長度為2.5cm、3.5cm、4.5cm及排列密度1cm、2cm、3cm下電磁波吸收值。由實驗得知，單層螺旋板材於長度4.5cm、排列密度2cm時吸收值可達19.38dB；疊層複合板材於長度4.5cm、孔徑0.5cm、排列密度2cm時電磁波吸收值最高可達33.54dB。疊層複合板材於孔徑0.5cm、長度3.5cm、排列密度3cm時頻寬率可達42.8%。 Under abstract this research clamp screw structure 2.5cm, 3.5cm, 4.5cm change its spiralaperture 0.3cm, 0.4cm, 0.5cm by different compactness lcm, 2cm, 3cm to discuss its electromagnetic wave absorption benefit. And its screw compound plate match different straightline compound plate length is 2.5cm, 3.5cm, 4.5cm and under compactness lcm, 2cm, 3cm theelectromagnetic wave absorption value. Knew by the experiment, single-layer spiral plate inlength3.5cm, when compactness 2cm absorbs the value to be possible to reach 19.38dB;Double-decked compound plate in length 4.5cm, aperture 0.5cm, when compactness 2cm theelectromagnetic wave abssorption value is highest may reach 33.54dB. The double-decked compound plate in aperture 0.5cm, length 3.5cm, the compactness 3cm time-frequency widthratio may reach 42.8%.
