    • Enhanced tunable plasmonic resonance in crumpled graphene resonators loaded with gate tunable metamaterials 

      Khattak, Muhammad Irfan; Ullah, Zaka; Al-Hasan, Mu’ath; Sheikh, Fawad (OSA - The Optical Society, 2020)
      Graphene devices have been widely explored for photonic applications, as they serve as promising candidates for controlling light interactions resulting in extreme confinement and tunability of graphene plasmons. The ...

    • Interparticle-Coupled Metasurface for Infrared Plasmonic Absorption 

      Ullah, Zaka; Nawi, Illani M.; Al-Hasan, Muath; Junaid, Muhammad; Mabrouk, Ismail Ben; Rehman, Abdul (Institute of Electrical and Electronics Engineers Inc., 2023)
      Plasmonic metasurfaces operating in the long-wavelength infrared region (LWIR) are primarily employed for bio-sensing and imaging applications. The key factor affecting the capability of LWIR metasurfaces is absorption ...
