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 ...

Design of one dimensional refractive index sensor using ternary photonic crystal waveguide for plasma blood samples applications

El-Khozondar, Hala J.; Mahalakshmi, Perumal; El-Khozondar, Rifa J.; Ramanujam, Nambi R; Amiri, I. S.; Yupapin, P. (Elsevier BV, 2019-07)

One dimensional ternary photonic crystal based refractive index sensor is numerically proposed for the blood plasma sensing applications. It is achieved by introducing the defects or cavity cell, where the blood samples ...

Electrical Energy Storage Technologies and the Application Potential in Power System Operation: A Mini Review

Diaz, P.M.; El-Khozondar, Hala J. (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

Penetration of renewable resources increases the global demand for high-efficient Energy Storage Technology (EST) that deals with reduction in the emission of green-house gases causing environmental hazards/pollutions, ...

Implementation of maker movement to renewable energy laboratory: case study of auto-tracking photovoltaic model

Al Afifi, Rafat; Pfeifer, Christoph; El-Khozondar, Hala (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

Maker-based education as well as research is a novel way to build self-designed tools on reasonable costs to perform tests with new methods and technologies. The application of maker movement (e.g. 3D printing, microcomputers, ...

Solar Energy Powered Toilet for Emergency or Remote Areas Usage: Maker Movement innovation

El-Khozondar, Rifa J.; El-Khozondar, Hala J.; Pfeifer, Christoph; Al Afifi, Rafat (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

In a time of catastrophes like war or earthquake, people forced to leave their houses and live in tents or remote areas. In both cases, utilities such as electricity, hot water, and probably toilet need to be provided ...

Switching mechanism for Off-Grid Hybrid Power System (Photovoltaic-Wind) with storage battery

El-Khozondar, Hala J.; Zainuddin, Siti Zafarh Bte; Koch, Alexander W (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

This work describes a modelling and simulation of the switching mechanism of an off-grid hybrid power system. An offgrid system means that it is not connected to an electricity grid or network. An off-grid power system ...

Recapitulation and comparative study for Photovoltaic Maximum Power Point Tracking techniques in particular sensor quality

El-Khozondar, Hala J.; yong, Lee Jun; Koch, Alexander W (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

In this study, a review on several maximum power point tracking (MPPT) algorithms is given. MPPT algorithms have three major categories: Conventional methods, Advanced Soft Computing methods and Hybrid algorithms. ...

Simulating the performance and output measurements of modeled Photovoltaic(PV) Inverter

Tan Wei Yen, Jim; El-Khozondar, Hala J.; Koch, Alexander W (Institute of Electrical and Electronics Engineers (IEEE), 2019-03)

In photovoltaics(PV) system, the Balance of System(BOS) describes the components that are connected to the PV Array which made up a PV system. In a grid-connected system, the PV inverter is a major part of the BOS. It ...
