Energy Exchange During Electron Emission from Carbon Nanotubes: Considerations on Tip Cooling Effect and Destruction of the Emitter

M. Dionne, S. Coulombe, and J. Meunier
Department of Chemical Engineering, McGill University, Montreal, Quebec, Canada

Murphy and Good general theory for electron emission from metal surfaces was used to predict the field-emission capabilities of ideal arrays of vertically aligned carbon nanotubes (VACNT). The Nottingham effect was taken into account in order to explain experimental observation of a ... En savoir plus

Mode Conversion Losses in a Smooth Wall Circular Waveguide

R. Kumar[1], H. B. Pandya [1], S. Danani [1], P. Vasu [1], V. Kumar[1]
[1]ITER-India, Gandhinagar, Gujarat, India

The ITER-ECE transmission lines consist of smooth-wall circular waveguides, including miter bends and other components. The performance of the TL is crucial to ensuring that the requirements for the diagnostic to measure the plasma parameters are met. COMSOL Multiphysics® has a finite ... En savoir plus

Plasmonic Properties of Bimetal Nanoshell Cylinders and Spheres

K. Ehrhold[1], S. Christiansen[1,2], and U. Gösele[1]
[1]Max Planck Institute of Microstructure Physics, Halle, Germany,
[2]Institute of Photonic Technology, Jena, Germany

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 ... En savoir plus

Propagation of Cathode-Directed Streamer Discharges in Air

Y. Serdyuk[1]
[1]Chalmers University of Technology, Gothenburg, Sweden

Streamers are considered as main cause of electrical breakdown in air at atmospheric pressure. A streamer is an ionization wave propagating in neutral gas which is converted into low-temperature plasma behind its front. A streamer model is based on drift-diffusion approach where space ...

A Magnetohydrodynamic Study of a Inductive MHD Generator

A. Montisci[1] and R. Pintus[1]

[1]Department of Electrical and Electronic Engineering, University of Cagliari, Cagliari, Italy

The aim of the proposed device is to overcome the typical drawbacks of MHD generators, such as the needed of a very high external magnetic field, the strong dependency of the efficiency by the temperature of the fluid, and the deterioration of the electrodes that are in contact with the ...

Finite Element Analysis of TTFields in Brain Metastasis According to Various Types of Cerebral Edema

S. Pisati[1], P. San[1], E. Lok[1], E. Wong[1]
[1]Beth Israel Deaconess Medical CEnter, USA

Background: TTFields are being investigated for treatment of brain metastasis. Although vasogenic edema is the most common type of associated cerebral edema, other forms of edema might arise within the brain due to prior treatment or other confounding effects. Therefore, we seek to ... En savoir plus
