【摘要】：新型人工電磁材料是一種人工復(fù)合材料,其電磁特性取決于材料的微結(jié)構(gòu),和它本身的構(gòu)成材料無關(guān)。它擁有著自然界常規(guī)材料所不具有的優(yōu)異物理性質(zhì),對(duì)電磁波有著超強(qiáng)的控制能力。同軸線作為電磁波傳輸中的一種重要媒質(zhì),應(yīng)用在許多重要領(lǐng)域。本文基于散射參數(shù)測(cè)量的參數(shù)提取方法,對(duì)一個(gè)外部隱形衣和同軸線測(cè)試系統(tǒng)進(jìn)行了相關(guān)的研究和分析。介紹了新型人工電磁材料、新型人工電磁材料器件的研究背景和發(fā)展歷史,以及新型人工電磁材料的特點(diǎn)和實(shí)現(xiàn)方法,并對(duì)實(shí)現(xiàn)隱形的機(jī)理作了相關(guān)解釋。文章還闡述了同軸線的有關(guān)知識(shí)和傳輸特性。通過對(duì)經(jīng)典的光學(xué)變換理論的解釋,進(jìn)一步來研究以此為理論依據(jù)所制備的一個(gè)外部隱形衣。由于解析的方法很難獲得新型人工電磁材料的電磁表達(dá)式,我們使用了基于散射參數(shù)測(cè)量的參數(shù)提取方法,來對(duì)它進(jìn)行相關(guān)分析。文章利用矢量網(wǎng)絡(luò)分析儀和射極跟隨器對(duì)外部隱形衣測(cè)試電路進(jìn)行了改進(jìn),并通過仿真軟件對(duì)它進(jìn)行研究,比較測(cè)試和仿真結(jié)果。通過對(duì)同軸線測(cè)試系統(tǒng)的研究,證明了基于散射參數(shù)測(cè)量的同軸線測(cè)試法對(duì)于研究材料電磁特性的可行性。利用仿真反演的方法,以及與理論值的對(duì)比,我們得到了不同情況下介質(zhì)環(huán)的電磁參數(shù)的誤差,這為后期實(shí)測(cè)提供了誤差數(shù)據(jù)的參考。我們的研究表明,基于散射參數(shù)測(cè)量的參數(shù)提取方法,在測(cè)試人工電磁材料的屬性上,具有操作簡(jiǎn)單、容易實(shí)現(xiàn)的優(yōu)勢(shì),有著重要的實(shí)際應(yīng)用價(jià)值。隨著新型人工電磁材料器件發(fā)展的美好前景,定會(huì)在未來發(fā)揮越來越重要的作用。
