The reduction of energy consumption in the building sector (nearly 40% of the energy consumption in Europe) is a real challenge to achieve the objective of the “2020 European climate and energy package”. In recent years, great interest is observed for the Stirling thermoacoustic machines. Nonlinearities due to the high level of acoustic pressure generate DC flows that are superimposed on the ...

Electric field distribution along an insulator surface is of prime importance for the long term performance of insulators. In this paper electric field and potential distribution along a standard 33 kV polymeric insulator were investigated under different pollution conditions. Effect of voltage type and polarity on the electric field and potential distribution under contaminated conditions were ...

Impedance spectroscopy is a measurement technique that has been investigated in a wide variety of medical applications. An example is the measurement of the dielectric properties of the skin and underlying tissue using sensors placed in contact with human skin with capacitive fringing field electrodes. The aim of this work is to use finite element methods for optimizing the sensor design ...

The need for high storage capacitors led to the development of polymer based capacitors. Polymers have high processability, mechanical flexibility, electrical breakdown strength and compatibility with printed circuit board (PCB) technologies; but usually have very low permittivity (K). In COMSOL Multiphysics software, the AC/DC module is selected and the In-plane electric currents are applied ...

The study of multiphase flows inside the microfluidic devices has received much attention recently because of its applications in heat and mass transfer, mixing, microreaction, emulsification and most importantly in MEMS and lab-on-a-chip. We study the influence of an electric field on the interfacial morphologies and their transitions, the phenomenon termed electrohydrodynamics. The literature ...
Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection sensitivity may not be sufficient when the size of the detection target is in nanoscale. To change this, we ...

Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous limitations interms of performance, stability and size. One way to overcome the limitations is to use thin ...

This paper presents the fast computational and modeling of multiconductor transmission lines interconnect in non-homogenous multilayered dielectric media using the finite element method (FEM). We illustrate the potential distribution of the multiconductor transmission lines for the models and their solution time. We compared some of our results of computing the capacitance matrix with method of ...

In this paper, we consider the finite element modeling of multilayer transmission lines for high-speed digital interconnects. Using COMSOL we mainly focused on the modeling of the transmission structures with both cases of symmetric and asymmetric geometries. We specifically designed asymmetric coupled microstrips and four-line symmetric coupled microstrips with a two-layer substrate. We ...

Cochlear Implants (CIs) are implantable prostheses that bypass the non-functional inner ear and directly stimulate the auditory nerve with electric currents, enabling deaf people to experience sound again. The CI electrode array sits inside the cochlea close to the auditory neurons. An ideal stimulation material must have low impedance with maximum charge transfer capacity in the electrochemical ...
