Highly sensitive nano-sensor based on a binary photonic crystal for the detection of mycobacterium tuberculosis bacteria

Taya, Sofyan A.; Daher, Malek G.; Colak, Ilhami; Ramahi, Omar M. (Springer Science and Business Media LLC, 2021-12)

Tuberculosis is a widespread disease all over the world. Early diagnosis plays a crucial role in the treatment of patients and can reduce the mortality rate. A new biosensor based on a binary photonic crystal is designed ...

Dispersion curves of a slab waveguide with a nonlinear covering medium and an exponential graded-index thin film (transverse magnetic case)

Taya, Sofyan A.; Hussein, Aya J.; Ramahi, Omar M.; Colak, Ilhami; Chaouche, Youcef Braham (The Optical Society, 2021-11-01)

"A slab waveguide that comprises a linear substrate, an exponentially graded-index guiding layer, and a power- dependent refractive index covering medium is investigated. All layers are assumed dielectric. The guiding ...

Modelling of three tunable multichannel filters using Ag metal as a defect layer in a photonic crystal

Taya, Sofyan A.; Abutailkh, Mariam A.; Colak, Ilhami; Ramahi, Omar M. (Springer Science and Business Media LLC, 2021-11)

"Three optical multi-color flters are modelled in the current work. They are composed of defective photonic crystals of two layers A and B and a defect layer C which is selected as silver Ag. The three multi-color flters ...

Properties of band gap for p-polarized wave propagating in a binary superconductor-dielectric photonic crystal

Taya, Sofyan A.; Doghmosh, Nael; Abutailkh, Mariam A.; Upadhyay, Anurag; Nassar, Zaher M.; Colak, Ilhami (Elsevier BV, 2021-10)

" A photonic crystal (PC) having the structure (AB)NA is investigated. A and B are superconductor and dielectric layers, respectively. P-polarized (TM) wave is assumed to be incident on the PC. The transmission of TM ...

Enhancement of optical visible wavelength region selective reflector for photovoltaic cell applications using a ternary photonic crystal

Doghmosh, Nael; Taya, Sofyan A.; Upadhyay, Anurag; Olaimat, Melad M.; Colak, Ilhami (Elsevier BV, 2021-10)

" In a recent study, the authors proposed an optical broadband angular reflector having a band selective feature and high reflectivity rate for possible applications in photovoltaic applications using a binary photonic ...

Cancer cell detector based on a slab waveguide of anisotropic, lossy, and dispersive left-handed material

Taya, Sofyan A.; Colak, Ilhami; Suthar, Bhuvneshwer; Ramahi, Omar M. (The Optical Society, 2021-09-20)

"Cancer is a disease that takes place when human cells grow uncontrollably. When detected and cured early, it can be non-life-threatening. It becomes life-threatening in case of late discovery where it affects the ability ...

Experimental investigation of zinc sodium borate glass systems containing barium oxide for gamma radiation shielding applications

Aboalatta, A.; Asad, J.; Humaid, M.; Musleh, H.; Shaat, S.K.K.; Ramadan, Kh; Sayyed, M.I.; Alajerami, Y.; Aldahoudi, N. (Elsevier BV, 2021-09)

Sodium zinc borate glasses doped with dysprosium and modified with different concentrations of barium oxide (0e50 mol %) were fabricated using the melting quenching technique. The structural properties of the prepared ...

Musalam, Alaa M.A.; El-Ashgar, Nizam M.; Abunamous, Raed E. S. (King Faisal University, 2021-09-01)

This study aimed to evaluate the security and safety procedures at the Islamic University of Gaza. Two major areas were focused on: the availability of security and safety procedures at the university and also what particular ...

Emergency management to avoid the spread of the COVID‐19 pandemic in Gaza Strip

Musalam, Alaa M. A.; Abunamous, Raed E. S.; El‐Ashgar, Nizam M.; Alhana, Ahmed S. (Wiley, 2021-09)

Gaza Strip is exposed to the danger of the novel coronavirus pandemic ""nCOVID-19"" spread, which exacerbates the crises severity on this besieged area since 2007. This study aims to identify the preventive actions during ...

An ultra-high birefringent and nonlinear decahedron photonic crystal fiber employing molybdenum disulphide (MoS2): A numerical analysis

Upadhyay, Anurag; Singh, Shivam; Sharma, Divya; Taya, Sofyan A. (Elsevier BV, 2021-08)

"A novel Decahedron photonic crystal fiber (DHn-PCF) is proposed. To sustain high birefringence and nonline- arity, the central elliptical core is filled with a highly nonlinear 2D material molybdenum disulphide (MoS2). ...
