Quantum Dots (QDs) laser is expected to have a low threshold current density and high thermal stability. We propose the QDs laser with the half-etched mesa distributed feedback (HEM DFB) structure. We accurately calculated the coupling coefficient in a HEM waveguide using the finite ... En savoir plus

The prediction of the exact location and intensity of the electric field induced in the human brain during Transcranial magnetic stimulation is a nontrivial computational task. Numerical simulations of the procedure can be used to acquire first approximations in a safe and controlled ... En savoir plus

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 ... En savoir plus

Magnetic grippers are commonly used for workholding in handling and assembly of ferrous metalcasted parts. The workholding force produced by the magnetic gripper is strongly influenced by the texture and form of the workpiece in contact with its surface. This work explores the optimal ... En savoir plus

The design of a magnetic resonance imaging (MRI) RF coil using finite element method-based analysis is an essential part of a multi-year research project at the National Institute of Standards and Technology, Gaithersburg, Maryland, where the goal of the project is to develop a “phantom” ...

In this paper simulation and parametric study of a PDMS valveless micropump using Fluid-Structure Interaction (FSI) appraoch is presented. The simulation for the valveless micropump were carried out in COMSOL Multiphysics software. In case of a valveless micropump diffuser/nozzle element ... En savoir plus

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 ... En savoir plus

INTRODUCTION: Micro Electro Mechanical Systems (MEMS) are fabricated with an in-plane fabrication technology. Out-of-plane structures can be designed to be assembled to provide thermal and electrical isolation from the substrate [1 -3]. These isolations can potentially improve the ... En savoir plus

Introduction: Vibration energy harvester can convert mechanical vibration energy into electrical energy and store it in battery for later use. It can create clean renewable energy from vibration movements such as walking, jumping, running, etc. This can convert energy previously wasted ... En savoir plus

Bioreactor landfill is based on a homogeneous distribution of the moisture content to increase waste biodegradation. Most of studies have shown that Electrical Resistivity Tomography (ERT) can be a suitable method to study water content variation (2D and 3D). ERT is influenced by many ... En savoir plus
