Abstract:	本研究是改變電磁波入射角，藉以探討不同的電磁波入射角對電磁波吸收體吸收效果的影響。利用不同電磁波入射角的變化經由雙脊喇叭天線、網路分析儀測量出對電磁波吸收體（針織、平板、塗佈）所造成吸收效果的不同，探討最佳吸收體與角度關係之影響。結論得知，吸收體的結構，以及吸收體內的金屬含量與種類，都會對於吸收效果有所影響，經由實驗結果發現，雙層5%不鐫鋼混紡平板織物吸收體在15度角能達到最好的吸收效果，其最大衰減值為31.315dB。 In the studying, the incident angles of the electromagnetic waves were changed in order to discuss the efficiency of absorbing with different incident angles. Analyzing the influence of switching incidental angles on different kinds of metallic electromagnetic absorbers (Knitting, shuttling, and coating) with Double Ridged Waveguide Hom and Vector Network Analyzer to find out the best relationship between incidental angels and absorbers. In conclusion, the construction of the absorber, the type of metal in the absorber, and the amount of metal in the absorber affect on the absorbing quality. From the experiment, double layers of shuttling absorber mixed with 5% of stainless steal has a best result at 15 degree incident angle, and it can reduce 31.315dB of the electromagnetic waves.
