Spectroscopic study of emitter assemblies coupled to Plasmonic nano-cavities and metamaterials
The plasma oscillations of noble metals as silver and gold are well understood from the free electron model of metals. In the past two decades, due to the availability of various physical and chemical fabrication methods ... -
Spin Hall Effect Mediated Current Induced Magnetization Reversal in Perpendicularly Magnetized Pt/Co/Pt Based Systems
(2018-02-08)In the present thesis, magnetization reversal in both out-of-plane and in-plane magnetized thin lms and in devices fabricated out of those lms are explored. Pt/Co/Pt stacks with ultrathin Co layer were in-estimated initially ... -
Spiral- And Scroll- Wave Dynamics In Ironically And Anatomically Realistic Mathematical Models For Mammalian Ventricular Tissue
(2017-05-24)Cardiac arrhythmias, such as ventricular tachycardia (VT) and ventricular fibrillation (VF), are among the leading causes of death in the industrialized world. There is growing consensus that these arrhythmias are associated ... -
Spiral-Wave Dynamics in Ionically Realistic Mathematical Models for Human Ventricular Tissue
(2018-04-18)There is a growing consensus that life-threatening cardiac arrhythmias like ven- tricular tachycardia (VT) or ventricular fibrillation (VF) arise because of the formation of spiral waves of electrical activation in cardiac ... -
Sputter Deposited Thin Film Cathodes from Powder Target for Micro Battery Applications
(2018-07-16)All solid state Li-ion batteries (thin film micro batteries) have become inevitable for miniaturized devices and sensors as power sources. Fabrication of electrode materials for batteries in thin film form has been carried ... -
Sputter Deposited ZrC and NbC Thin Films – Studies on Microstructure, Texture and Hardness
(2018-08-29)Transition metal carbides have great industrial importance with a wide area of applications. Unlike many ceramic materials which can be produced from raw materials found in nature, the refractory carbides generally do not ... -
Stability of Accretion Flows And Radiative-Hydrodynamics Around Rotating Black Holes
(2013-06-24)In the case of cold accretion disk, coupling between charge neutral gas and magnetic field is too weak such that the magneto-rotational instability will be less effective or even stop working. In such a situation it is of ... -
Stabilization Schemes for Convection Dominated Scalar Problems with Different Time Discretizations in Time dependent Domains
(2018-05-21)Problems governed by partial differential equations (PDEs) in deformable domains, t Rd; d = 2; 3; are of fundamental importance in science and engineering. They are of particular relevance in the design of many engineering ... -
