Son zamanlarda mükemmel soğurucular (MS), karmaşık elektriksel ve manyetik geçirgenlik özelliklerinden dolayı büyük ilgi görmüştür. Bu yapay yapıları rasyonel bir şekilde tasarlayarak, mükemmel soğurucunun empedansı, elektrik ve manyetik rezonanslarda bağımsız bir ayarlama ile boş alana eşleştirilebilir; ve böylece oluşturulan yapı, orta ve yakın kızılötesi dalga boylarında güçlü soğurmaya yol açar. Özellikle metal-dielektrik bazlı plazmonik metamalzemelerden oluşan nanoyapılar, güçlü yakın alan geliştirme, negatif kırılma indeksi ve optik gizleme gibi benzersiz optik özellikler sergiler. Bu çalışmada, metamalzeme tabanlı farklı rezonanslarda aynı anda %100’ e yakın bir soğurumla çalışan iki bantlı U şeklinde antenlerden oluşan bir MS platformu önerilmiştir. MS platformunun ince ayar mekanizması için sonlu fark zaman alanı (FDTD) simülasyonları aracılığıyla optik yanıtının geometrik parametrelere bağımlılığı sayısal olarak analiz edilmiştir. Soğurum tepkisini ve yakın alan dağılımlarının fiziksel temelleride sayısal olarak incelenmiştir. Sayısal hesaplamalarımız, ikili rezonanslarda U plazmonik anten sisteminin geniş ve kolayca erişilebilen yerel elektromanyetik alanları desteklediğini göstermektedir. Deneysel sonuçlar, teorik hesaplamalar ile oldukça uyumludur. Çift rezonanslı U şekilli antenler sahip oldukları güçlü ve erişilebilir elektromanyetik alandan dolayı güçlü yakın alan özelliklerine sahiptir ve çok sayıda spektral özellik gerektiren birçok uygulama için oldukça avantajlı olabilir. Ayrıca, önerilen U şekilli plazmonik antenlerin rezonans frekansı spektral olarak ayarlanabildiği için aktif filtreler, optik modülatörler, ultra hızlı anahtarlama cihazları, haberleşme, detektör ve biyoalgılama gibi çok çeşitli uygulamalar için de kullanılabilir.

Recently, perfect absorbers (PAs) have attracted great attention due to their complex electrical permittivity and magnetic permeability properties. By rationally designing these artificial structures, the impedance of the perfect absorber can be matched to the free space with an independent adjustment in electric and magnetic resonances; and the structure thus leads to strong absorption from mid-IR to near-IR wavelength. Especially, metal-dielectric based plasmonic metamaterials in nanometer scale exhibit unique optical properties such as strong near field enhancement, negative refractive index and optical cloaking. In this study, we propose a dual-band metamaterial base PA platform consisting of U-shaped antennas with unity absorption. We numerically analyzed the dependence of the optical response on geometric parameters through finite difference time domain (FDTD) simulations for the fine tuning mechanism of the PA platform. The physical basis of the absorption response and near-field distributions of these nanoscale antennas were also studied numerically. Our numerical calculations show that U-shaped plasmonic antenna system supports large and easily accessible local electromagnetic fields. Experimental and theoretical results are found to be in good aggrement. U-shaped antennas with dual resonances with large and accessible electromagnetic fields can be highly advantageous for a wide variety of applications that require a large number of spectral features with strong near field properties. In addition, since the resonance frequency of the proposed U-shaped plasmonic antennas can be adjusted spectrally, they can also be used for a wide variety of applications such as active filters, optical modulators, ultra-fast switching devices, communication, detectors and biosensing.
