The experiment results indicated that conditional on transforming layer 1mm thick and absorbing layer 2mm thick , the combined materials which were processed by 600 and 800 respectively have good absorbing performance , and the influence of the combing sequence on absorbing performance is indistinctive
實(shí)驗(yàn)表明，當(dāng)變換層為1mm ，吸收層為2mm時(shí)，以600處理的和800處理的材料進(jìn)行不同組合都有較好的吸波性能。
The combination absorbs microwave well with the least reflectivity of - 31 . 59db , and minimally having 2 . 31ghz - frequency band . these results illuminated the directional law of combined materials , it is that , when the double deck with the different thickness , no matter what is absorbing or transforming layers , its absorbing performance would not be influenced on the whole . when the double deck with the same thickness , the combining sequence of materials would cause crucial influence on its absorbing performance
在8 . 2 12 . 4ghz頻段內(nèi)，最小反射率達(dá)- 45 . 93db ，有效頻寬為4 . 0ghz ；當(dāng)變換層和吸收層厚度相同，總厚度為2mm時(shí)，要獲得較好的吸波性能，必須以高溫處理的材料作變換層，低溫處理的材料作吸收層，即存在材料組合的方向性，其中以1000分別與600 、 700處理的材料組合性能最佳，其最小反射率為- 31 . 59db ，有效頻寬最小為2 . 31ghz 。
