Estimation of Variablities due to Stochastic Variation in Geometric Parameters in Microwave Applications

A. B. N.[1], K. Vinoy[1]
[1]Indian Institute of Science, Bangalore, India

Predicting the stochastic behaviour of electromagnetic systems is important in microwave circuit in applications such as terahertz, millimetre wave circuits, resonating structures, substrate integrated waveguides etc. Computational cost in predicting the variations due to the stochastic ...

Investigation of Geometry and Positioning Influence on Optical and Thermal Properties of Gold Nanoparticles.

R. Deska[1], J. Olesiak-Bańska[1], K. Matczyszyn[1]
[1]Wroclaw University of Technology, Poland

In COMSOL Multiphysics® RF Module we investigate optical properties of various shapes of gold nanoparticles suspended in water and deposited on a glass substrate. Further, using the Microwave Heating Multiphysics coupling we want to evaluate heating effects related to electromagnetic ... En savoir plus

Modeling the interaction of terahertz radiation with human skin

Shaoxin Huang [1],
[1] Peking university

This paper presents the modeling of interaction between terahertz radiation and human skin. By doing so, we can differentiate between the healthy skin and the cancerous skin (BCC). We set a square region as the cancerous skin, surrounded by the healthy skin. Since the biological tissues ... En savoir plus

Microwave Radiation to Cure Cork Stoppers Using a Conventional Turntable Configuration

D. Fidalgo[1], J. Monteiro[1], L. Costa[1]
[1]I3N and Physics Department, University of Aveiro, Aveiro, Portugal

This work presents an alternative method for curing cork stoppers based on microwave radiation, which is energetically more efficient, where it is possible to accelerate the reaction rate and therefore reduce the cure time comparatively with conventional curing methods. The microwave ... En savoir plus

Simulation of Optical Ring Resonator Based on Lithium Niobate on Insulator

H. Kumar [1], V. Janyani [1], B. Oleh [2], U. Serhij [2], S. Dmytro [2], G. Singh [1],
[1] Dept. of Electronics and Communication Engg., Malaviya National Institute of Technology Jaipur, India
[2] Inst. of Tele. Radioelectronics and Electronic Engg.,Lviv Polytechnic National University, Lviv, Ukraine

In this paper, all optical microring resonator based on Lithium Niobate on Insulator (LNOI) has been proposed. LNOI has high refractive index contrast and also show better electro-optic & acousto-optic effects. The optical ring resonator resonates when the optical path-length of the ... En savoir plus

Extraordinary Optical Transmission in Copper-Based Devices at Terahertz Frequencies

S. Almousa [1], J. A. Deibel [1],
[1] Department of Physics, Wright State University, Dayton, OH, USA

While low frequency light is poorly transmitted through an aperture in a conductive thin film, in the phenomenon known as extraordinary optical transmission (EOT), a narrow band of selected frequencies are transmitted when incident on an array of subwavelength periodic apertures where ...

Light Scattering by Subwavelength Arrays of Silicon Nanowires

M.l. Urbaneja Torres, A. Manolescu
School of Science and Engineering, Reykjavík University, Reykjavík, Iceland

The study of light scattering by optically resonant nanostructures is a field of growing interest as a result of the rapid progress in nanophotonics in the last decade. Contrary to their plasmonic counterparts, high-index dielectric structures exhibit low optical losses and different ... En savoir plus

Influence of Micro Gaps on the Magnetic Characteristics of FI Relay

L. Strehar [1], D. Janc [1], A. Smrkolj [1], A. Pušnik [1], N. Štrovs [1],
[1] ETI d.o.o., Izlake, Slovenia

Various types of FI-Relays are built in electrical protective residual current devices (RCD). They are all electromechanical assemblies that trip at appearance of residual currents (i.e. fault or earth leakage current) and consequently break main contacts of RCD. FI relays are very ...
