    • Optical fiber surrounded by a graphene layer as an optical sensor

      Al-Ashi, Noor E.; Taya, Sofyan A.; El-Naggar, Sahar A.; Vigneswaran, D.; Amiri, I. S. (Springer Science and Business Media LLC, 2020-03)
      "An optical sensor composed of a circular cylindrical fber surrounded by graphene layer is investigated. The thin layer of graphene is located at the core–cladding interface. The cladding is an aqueous material. The ...
    • The design and analysis of a dual‑diamond‑ring PCF‑based sensor

      Paul, Bikash Kumar; Ahmed, Kawsar; El-Khozondar, Hala J. (Springer Science+Business Media, LLC, part of Springer Nature 2020, 2020)
      A dual-diamond-ring photonic crystal fber (PCF)-based sensor is proposed and analyzed herein for the detection of the concentration of alcohol in aqueous solution. Commercially available fnite element method (FEM)-based ...
    • Transverse magnetic mode slab waveguide optical sensor in the presence of conducting interfaces

      Vadivu, N. Shanmuga; Mahdi, Sameh S.; Taya, Sofyan A.; Alkanoo, Anas A.; Qadoura, Ibrahim M.; Mahalakshmi, P.; Mani Rajan, M.S. (Elsevier BV, 2019-02)
      "In this paper, three –layer slab waveguide is considered for the p-polarization whose free charge layer with a surface conductivity is assumed to exist at the two interfaces. The structure is then enhanced for sensing ...
