Abstract

In this study, a metamaterial based microwave absorber working at three microwave bandwidths was designed. The design works with 90% absorption in 3 different microwave bands, namely C band between 5.4-7.75 GHz, X band between 8.3 - 9.65 GHz and Ku band between 13.65 - 15 GHz respectively. The polarization of the wave incoming to the designed metamaterial absorber was changed, and the percent absorption was obtained exactly the same with the metamaterial geometry for TE and TM modes. In this respect, it is polarization insensitive absorber, and strong absorption results have been obtained at various oblique incidence (10o, 20o and 30o) for absorption performance. For the analysis of the microwave absorber, the electrical and magnetic permeabilities of the metamaterial were obtained in resonance. In addition, for impedance analysis, the normalized impedance of the metamaterial in the absorbing operating frequency range was obtained. In the frequency ranges where absorption is provided, the normalized impedance value of the absorber has been obtained approximately the same as the normalized impedance of the air. In addition, the surface currents of the metamaterial absorber were obtained for the frequencies 5.67 GHz, 7.37 GHz, 8.76 GHz and 14.43 GHz where strong resonance frequencies were realized. CST Microwave Studio is used as an electromagnetic simulation program.

Abstract

Bu çalışmada üç mikrodalga bant genişliğinde çalışan metamalzeme tabanlı mikrodalga emici tasarımı yapılmıştır. Gerçekleştirilen tasarım sırası ile 5.4-7.75 GHz aralığında C bandında, 8.3 - 9.65 GHz aralığında X bandında ve 13.65 – 15 GHz aralığında Ku bandında olmak üzere 3 farklı mikrodalga bant aralığında %90 emilim ile çalışmaktadır. Tasarlanan metamalzeme emiciye gelen dalga polarizasyonu değiştirilmiş, metamalzeme geometrisi ile TE ve TM modları için yüzde emilimleri birebir aynı elde edilmiştir. Bu yönüyle polarizasyon hassasiyetsiz emici olup, emilim performansı için çeşitli açılarda (10o, 20o ve 30o) güçlü emilim sonuçları elde edilmiştir. Mikrodalga emicinin analizi için rezonans bölgesinde metamalzemenin elektriksel ve manyetik geçirgenlikleri elde edilmiştir. Ayrıca empedans analizi için metamalzemenin emici çalışma frekans aralığında normalize empedansı elde edilmiştir. Emilimin sağlandığı frekans aralıklarında emicinin normalize empedans değeri yaklaşık olarak havanın normalize empedansı ile aynı olarak elde edilmiştir. Ayrıca güçlü rezonans frekanslarının gerçekleştiği 5.67 GHz, 7.37 GHz, 8.76 GHz ve 14.43 GHz frekansları için metamalzeme emicinin yüzey akımları elde edilmiştir. Güçlü rezonans frekanslarda maksimum yüzde emilim oranları referans alınan diğer çalışmalarla karşılaştırılmıştır. Metamalzeme emicinin davranışının anlaşılması için transmisyon hattı eşdeğer devresi verilmiştir. Elektromanyetik simülasyon programı olarak CST Microwave Studio kullanılmıştır.
