Mükemmel soğurucu, sensör, ışınımsal ısı transferi, dalga ayırıcı ve 5G/ötesi uygulamarı için Van Der Waals tabanlı ayarlanabilir meta-yüzeyler

Metasurfaces are thin, subwavelength structures that have extraordinary properties that cannot be found naturally. Tunable metasurfaces drew attention not only for their lightweight designs but also with the tunning option, having multiple responses without complex fabrication steps for each desired response. Besides tuning the structures by their intrinsic properties, the addition of van der Waals materials which are a specific type of 2D materials, can expand their tuning flexibilities and offer a wide range of applications. Here, we propose and investigate tunable metasurfaces in the following areas: Perfect Absorption, Sensing, Radiative Heat Transfer, Beam Splitting and 5G/Beyond Applications as: 1. All-Dielectric Metamirror for thermally tunable spectrally selective absorber, 2. Metasurface Design for Phonon-Induced Transparency and Nearly Perfect Resonant Absorption, 3. Near-Field Radiative Heat Transfer in Parallel-Plate Structures, 4. Gradient Metasurfaces for Beam Splitting and Light Absorption, 5. 5G and Beyond applications of mentioned works and future outlook.
