A Novel Generalized Scattering Through Heterostructure With A Time-Periodic Potential
Al-Sahhar, Zeyad I; Shabat, Mohammed M. (2006)Interaction with external time-dependent fields in low-dimensional systems leads in many cases to completely new phenomena of electronic transport. Dealing with a driven system, its quantum dynamics is adequately analyzed ... -
Bound States Revealed in a Heterostructure with Time-Periodic Potential
Al-Sahhar, Zeyad I; Shabat, Mohammed M. (IEEE, 2006)In the present work we study the resonances of a one-dimensional potential barrier driven by an external periodic force considering the position-dependent-effective-mass PDEM formalism. We used the Floquet scattering matrix ... -
Floquet Scattering Through a Heterostructure in a Time-Periodic Potential
Al-Sahhar, Zeyad I; Shabat, Mohammed M. (2008)We studied the resonances of a one-dimensional potential barrier driven by an external periodic force considering the Position Dependent Effective Mass (PDEM) formalism. The Floquet S matrix will be constructed then the ... -
Magnetostatic surface waves propagation at the interface between ferrite and MTMs parallel plate waveguide structure
Al-Sahhar, Zeyad I; El-Khozondar, Hala J.; Shabat, Mohammed M. (2013)Accepted 10/6/2013 Abstract: This work considers magnetostatic surface waves propagation in parallel structure composed of ferrite film bounded from below by metamaterial (MTM) placed on metal substrate and from top by ... -
Nonlinear magnetostatic surface waves guided by a single ferroelectric interface
Al-Sahhar, Zeyad I; Shabat, Mohammed M. (Abdus Salam International Centre for Theoretical Physics, 2003)In this communication, an exact analytical solution of magnetostatic surface waves propagating along the boundary of a single interface of nonlinear ferroelectric cover and a linear frequency dependent ferrite is derived ... -
Propagation of Electromagnetic Surface Waves through a Ferrite Slab Bounded by Metamaterials
Al-Sahhar, Zeyad I; El-Khozondar, Hala J.; Shabat, Mohammed M.Recently there has been growing interest in a new type of electromagnetic materials called lefthanded materials (LHMs), or metamaterials. Over thirty years ago Veselago [1] predicted that electromagnetic wave propagation ... -
Propagation of polaritons in GaAS/AlGaAS heterojunction with left handed materials waveguide structure in quantizing magnetic field
Al-Sahhar, Zeyad I; Hamada, Majde S.; Husein, Abdel Hakeim M.; Shabat, Mohammed M.A theoretical investigation of nonradioactive surface polaritons in GaAs/Al x Ga 1-x metamaterials (left-handed material-LHM) waveguide is presented. The real heterojunction with LHM under both conditions is favoring ... -

Al-Sahhar, Zeyad I; Hamada, Majde S.; Shabat, Mohammed M. (Al-Aqsa University, 2014)يتم تقديم التحقيق النظري لسطح البولاريتونات غير المشعة في المواد الفوقية GaAs/AlxGa1-x (أيسر المواد LHM) كدليل موجي. نقطة الاتصال المختلفة الحقيقية مع LHM في ظل الظروف وتفضيل العدد الصحيح الكمي لتأثير هول (IQHE) ووجود تبديد ... -
Sensitivity Evaluation of Graphene-Left Handed Waveguide Sensors
Shabat, Mohammed M.; Abushaar, Khoulud KH; Al-Sahhar, Zeyad I (American Scientific Publishers, 2017)In this paper, we present a theoretical investigation of a proposed waveguide sensors containing artificial graphene-left hand materials. The graphene is represented by an infinitesimally thin local and isotropic two-sided ... -
The Sensitivity of TE Filed Propagating in LHM-Antiferromagnetic Sensor
Al-Sahhar, Zeyad I; El-Khozondar, Hala J.; Shabat, Mohammed M. (David Publishing Company, Inc., 2014)A three-layer waveguide structure sensor consists of LHMs (left-handed materials) film surrounded by dielectric cladding and antiferromagnetic substrate is proposed. LHMs known as MTMs (metamaterials) have simultaneous ... -
