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 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 ...

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 ...
