Estimated View of Renewable Resources as a Sustainable Electrical Energy Source, Case Study

Al-Najjar, Heyam; Pfeifer, Christoph; Al Afifi, Rafat; El-Khozondar, Hala J. (2020)

Renewable energy resources for energy generation in the Gaza Strip (GS) emerge as a complementary resource, not only to meet the need of society for energy in various forms, but also to find available, sustainably, and ...

Performance Investigation of 1.6 Tbps Hybrid WDM-PDM-OFDM-based Free Space Optics Transmission Link

Singh, Mehtab; Malhotra, Jyoteesh; Atieh, Ahmad; El-Khozondar, Hala J.; Dhasarathan, Vigneswaran (The final publication is available at link.springer.com, 2020)

A novel ultra-high capacity free space optics (FSO) link has been developed by incorporating hybrid wavelength divison multiplexing (WDM)-polarization division multiplexing (PDM)-orthogonal frequency division multiplexing ...

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 ...

Highly Efficient Solar Energy Conversion Using Graded-index Metamaterial Nanostructured Waveguide

El-Khozondar, Hala J.; El-Khozondar, Rifa J.; Shama, Abhishek; Ahmed, Kawsar; Dhasarathan, Vigneswaran (2020)

In this paper, a graded-index metamaterial (GIM) nanostructured waveguide is proposed to enhance the performance of solar cells via a tunable absorption spectrum. The proposed four-layer nanostructured waveguide consists ...

Design of one dimensional defect based photonic crystal by composited superconducting material for bio sensing applications

Ramanujam, Nambi R; El-Khozondar, Hala; Vigneswaran, Dhasarathan; Taya, Sofyan A.; Aly, Arafa (Elsevier BV, 2019-11)

A novel biosensor based on 1-D defect photonic crystal is suggested to be consisting of alternate layers of SiO2 and Air. At the middle, there exists a cavity layer encapsulated with a composite layer of superconducting ...

Study of Utilization of Embedded Metal Nanoparticles in Dielectric Thin Film for Humidity Sensing

El-Khozondar, Hala J.; Mohammed, Waleed (Springer Science and Business Media LLC, 2019-09-30)

This paper presents a theoretical study of the utilization of the shift in the reflection peak of the thin dielectric film with embedded metal nanoparticles (NPs) towards humidity and vapor applications. The presence of ...

High birefringent, low loss and flattened dispersion asymmetric slotted core-based photonic crystal fiber in THz regime

Monir, Md. Khairum; Hasan, Mahmudul; Paul, Bikash Kumar; Ahmed, Kawsar; El-Khozondar, Hala J.; Amiri, IS (World Scientific Pub Co Pte Lt, 2019-08-10)

This paper proposes a novel model to attain high birefringence and low loss in a slotted core-based photonic crystal fiber (PCF) structure in THz regime. The performance of the proposed PCF has been evaluated by applying ...
