Modeling of Lorenz Force Flowmeter for Molten Metal Flow Application

T. V. Shyam[1], B. S. V. G. Sharma[1], Mrigendra Kumar Mrityunjaya [2], Dr. Ravinder Agarwal[2]
[1]Reactor Engineering Division, Bhabha Atomic Research Centre, Mumbai, India
[2]Thapar University, Patiala, India

Flow measurement of molten metals is a formidable task considering the hostile conditions. Many electromagnetic methods have been evolved for measurement of flow of conductive medium. The Lorenz force velocimetry is promising considering its non-intrusive nature. The Lorenz force ... En savoir plus

Low-Loss Metallic Waveguide for Terahertz Applications

K.Singh [1], A.Sengupta [1], A.Bandyopadhyay [2],
[1] Indian Institute of Technology Delhi, New Delhi, India
[2] DRDO-JATC, New Delhi, India

Introduction: Terahertz waves (THz), also known as T-rays, range from 0.3 THz to 10 THz and hence positioned between Microwaves and Infrared radiations on the Electromagnetic spectrum. T-rays exhibit several distinctive properties which make these suitable for applications such as ... En savoir plus

Broadband Polarization-Independent and Wide-Angle Metasurface for Radar Cross Section Reduction

A. Vora [1], S. Joshi [2], D. Guney [1],
[1] Michigan Technological University, Houghton, MI, USA
[2] Touro College, New York, NY, USA

In the past few years, metamaterial perfect absorbers (MPA) have been extensively studied due to their incredible ability to manipulate electromagnetic waves and provide a broadband, polarization-independent, and wide-angle response for a host of applications. The need for high ... En savoir plus

COMSOL Aided Design of an Extraction Pipe for the Electron Beam from a Plasma Focus Device

M. Valentinuzzi[1], E. Ceccolini[1], D. Mostacci[1], M. Sumini[1], F. Rocchi[2]
[1]Montecuccolino Nuclear Engineering Laboratory, University of Bologna, Bologna, Italy
[2]UTFISSM-PRONOC, ENEA, Bologna, Italy

The electron beam emitted backward by Plasma Focus devices is being investigated as a radiation source for IORT (Intra-Operative Radiation Therapy) applications. A Plasma Focus device is being developed to this aim. The electron beam is driven through an electron pipe made of stainless ... En savoir plus

Modeling of Resonant Optical Trapping in a 2D Photonic Crystal Cavity

U.P. Dharanipathy[1], N. Descharmes[1], Z. Diao[1], M. Tonin[1], R. Houdré[1]
[1]Institut de Physique de la Matière Condensée, Ecole Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland

Photonic crystals (PhC) are optical nanostructures that are widely known for their strong spatial and temporal confinement of electromagnetic radiation. Here, we study the resonant optical trapping of a single nanoparticle within a hollow circular photonic crystal cavity. The ... En savoir plus

Electrical and Thermal Analysis of an OLED Module

J. Kundrata[1], A. Baric[1]
[1]Faculty of Electrical Engineering and Computing, University of Zagreb, Zagreb, Croatia

This paper presents the electrical and thermal analysis of an OLED module. The OLED module consists of the OLED tile and the DC-DC converter incorporated in its backplane. The DC-DC converter is realized as an integrated circuit and its inductor is embedded in the the backplane. The DC ... En savoir plus

Development of a 10 kW Microwave Applicator for Thermal Cracking of Lignite Briquettes

B. Lepers [1], G. Link [1], J. Jelonnek [1]
[1] Karlsruhe Institute of Technology, Institute for Pulsed Power and Microwave Technology, Karlsruhe, Germany

Introduction: The use of microwave energy for thermal cracking (from thermal stress and water pore pressure) of lignite-coal briquettes increases the lignite friability [1] and is beneficial for later chemical treatment inside a gasifier (for methanol production for example). An ... En savoir plus

Transformation Optics Simulation Method for Stimulated Brillouin Scattering

R. Zecca [1], P. T. Bowen [1], D. R. Smith [1], S. Larouche [1],
[1] Center for Metamaterials and Integrated Plasmonics and Department of Electrical and Computer Engineering, Duke University, Durham, NC, USA

Stimulated Brillouin scattering (SBS) is a nonlinear phenomenon coupling optical and elastic waves. Traditionally regarded as an undesirable side-effect, it has garnered renewed interest as a platform for investigating slow light, nonreciprocity, and for designing high-performance chip ...

Model of a Pulsed Radiofrequency Technique for Pain Relief

E. Ewertowska [1], M. Trujillo [2], E. Berjano [1],
[1] Department of Electronic Engineering, Universitat Politècnica de València, Valencia, Spain
[2] Instituto Universitario de Matemática Pura y Aplicada, Universitat Politècnica de València, Valencia, Spain

Radiofrequency ablation is one of the common methods used to treat pain, movement or mood disorders. It bases on the electromagnetic energy provided to the selected tissue when an alternating current is applied. The resistive heating produced in this process provokes temperature rise in ...
