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 ... -
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 ... -
Enhanced sensitivity of cancer cell using one dimensional nano composite material coated photonic crystal
Ramanujam, Nambi R; Amiri, IS; Taya, Sofyan A.; Olyaee, Saeed; Udaiyakumar, R; Pandian, A Pasumpon; Wilson, KS Joseph; Mahalakshmi, Perumal; Yupapin, PP (Springer Berlin Heidelberg, 2018)We theoretically analyze the detection of a cancer cell in the one-dimensional photonic crystal by infiltrating different sample cells in the cavity layer. The defect modes appear in their transmission spectra only if the ... -
Extension of energy band gap in ternary photonic crystal using left-handed materials
El-Amassi, Dena M; Taya, Sofyan A.; Ramanujam, Nambi R; Vigneswaran, Dhasarathan; Udaiyakumar, R (Academic Press, 2018)We investigate the extension of energy band gap in one-dimensional ternary photonic crystal. We assume one of the layers constituting the ternary photonic crystal to be left-handed material (LHM) of simultaneously negative ... -
Photonic crystal with epsilon negative and double negative materials as an optical sensor
Taya, Sofyan A.; Alkanoo, Anas A; Ramanujam, Nambi R; Mahalakshmi, Perumal; Vigneswaran, Dhasarathan (Springer US, 2018)Two ternary photonic crystals are proposed for sensing applications. The first one is composed of an air layer as an analyte sandwiched between two double negative material (DNM) layers whereas the second one consists of ...
