Non-charge-based logic is the notion that an electron can be trapped and its spin manipulated through application of gate voltages. Numerical simulations of Spin Single Electron Transistors (SSET) at University at Albany, aimed at practical development of post-CMOS concepts and devices is presented. We use COMSOL based multiphysics finite element simulation strategy to solve the ...

Plasmonic-based optical trapping is in its infancy and growing rapidly. Research in this area will significantly advance fundamental understanding in fields such as nanophotonics and biophotonics. Novel plasmonic trapping structures and systems can be designed and optimized using the COMSOL RF solver. We present a study of plasmonicbased optical trapping of neutral sub-wavelength ...

Plasmonics is a new branch of the fascinating field of photonics and develops concepts to quench light beyond the diffraction limit and enhance electromagnetic fields. These enhancements occur in metals as localized surface plasmon polaritons (LSP) a coupling of the surface density oscillations of the electron gas to the incident light. With threedimensional nano-structures of coinage metals that ...

The preferred acoustic response of recording studios, auditoriums and conference halls is to have an even energy response over the entire room and throughout full audio spectrum. This can be accomplished by using acoustic panels with complex surface structures that scatter acoustic waves and diffuse sound level variability over the room volume or through the use of sound absorbing materials to ...

The aim of this work is to present a simple multiphysics simulation using COMSOL able to describe combustion of kerosene vapours in a closed vessel. The emphasis is on the mechanical effects of the reactive processes. The evolution of the thermodynamical variables (pressure, temperature, concentrations…) is obtained by solving several coupled transport equations for: the mass continuity, the ...

Peristaltic pumping is an inherently nonlinear multiphysics problem where the deformation of the tube and the pumped fluid are strongly coupled. We used COMSOL Multiphysics to investigate the performance of a 180 degree rotary peristaltic pump with two metallic rollers, and an elastomeric tube pumping a viscous Newtonian fluid. The model captures the peristaltic flow, the flow fluctuations ...

Conductive Composites such as carbon fiber reinforced composites are increasingly used in safety critical aerospace applications. The catastrophic macro structural failure of composite structures initiates from a micro level failure event such as fiber breaks. The ability to detect damage early on can improve the safety level and reliability of composite structures. A multilevel self-sensing ...

Introduction: Improving the capability of nondestructive evaluations requires the analysis of suitable models dealing with the physical and mechanical phenomena involved in the experiments. For example, ultrasonic tests may be a powerful, fast and effective method for nondestructive characterization of mechanical properties of materials. This requires the study of the related elastodynamic ...

A COMSOL model of a piezoelectric quartz double ended tuning fork gyroscope was implemented. The gyroscope has two detection modes; the first mode detects the angular velocity about a z-axis perpendicular to the tuning fork plane (x-y plane), while the second mode detects the angular velocity about a y-axis that is the longitudinal axis along the length of the tuning fork. Eigenfrequency analyses ...

Induction furnaces are employed for vacuum distillation process to recover heavy metals after electro-refining operation. Induction furnace of suitable heating rate and cooled by passive means are required to be developed for this purpose. It is planned to set up a mock up induction furnace which will simulate the conditions to be realized in actual vacuum distillation furnace for this purpose. ...
