[1]Tata Institute of Fundamental Research, Homi Bhabha  Road, Mumbai,India

Since the advent of Terhertz(THz) technology, improving the THz emission power has been one of the major research goal. One of the methods to increase the THz emission power is to increase the coupling of excitation laser light to the dielectric substrate.The field of nano-plasmonics ... Mehr lesen

Singlet Oxygen Modeling for PDT Incorporating Local Vascular Oxygen Diffusion

T. C. Zhu[1], B. Liu[1]
[1]University of Pennsylvania, Philadelphia, PA, USA

Singlet oxygen (1O2) is the major cytotoxic agent that kills cells during photodynamic therapy (PDT). Based on a previously-developed model, the distance-dependent reacted 1O2 can be numerically calculated using finite-element method. We improved the model to include microscopic kinetic ...

Modeling of Transport Phenomena in Gas Tungsten Arc Welding of Ni to 304 Stainless Steel

A. Bahrami[1], D. K. Aidun[1]
[1]MAE Department, Clarkson University, Potsdam, NY, USA

COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ...

A Systematic Method for Producing Simulated Scattered Field Data from Known Structures

R. S. Ritter [1], M. A. Fiddy [2],
[1] Olivet Nazarene University, Bourbonnais, IL, USA
[2] University of North Carolina - Charlotte, Charlotte, NC, USA

One of the greatest challenges in developing algorithms for imaging from scattered fields is the lack of suitable scattered field data from known targets. It has proved quite difficult to acquire this data from measurements in the laboratory due the fact it can be costly, time ... Mehr lesen

Electrostatic Fluid Structure Interaction (EFSI) on the Huygens Experiment
