Abstract: Line resolution, uniformity and focusing are the three (3) most important factors in the use of electron-beam lithography to form either high resolution masks or direct-write device etch patterns. This paper will present the observations and analyses made from a group of COMSOL ... 詳細を見る

Research <em>in vitro</em> and in small animals has shown electric fields (EFs) induce directional migration in stem cells along an electrical potential gradient, a process known as cell electrotaxis, or cell galvanotaxis1,2. We built a first-pass COMSOL model to identify ... 詳細を見る

Sulfidation corrosion of Nickel based super-alloy turbine blades is one form of corrosion that adversely affects blade performance. It results in a depletion zone involving magnetic corrosive byproducts with a high relative permeability [1]. Magnetometers are sometimes used in non ... 詳細を見る

When a material is subjected to a sudden change in electric field, the polarization of the material takes a finite time to respond – this phenomenon is referred to as dielectric relaxation. Dielectric relaxation is critical to understanding the important analytic technique of impedance ... 詳細を見る

MEMS microphones consist of a conductive backplate and a conductive flexible membrane. The backplate and the membrane are at a certain distance from each other to be interpreted as parallel plates of a capacitor. When a bias voltage is applied to the electrodes, membrane deflection ... 詳細を見る

For many decades Helium-3 (3He) and Argon gas filled detectors have been used for neutron and gamma detection. Detection requires the generation of electrons which can then be measured by electronic means. These electrons are generated either directly through gamma ionization of a gas ... 詳細を見る

Organic Thin Film Transistors are simulated for gas sensing application. The simulation is performed using COMSOL Multiphysics® simulation software's Semiconductor Module. Drift-diffusion (DD) simulation model is used in which the basic equations used are similar to those used for a ... 詳細を見る

Micro shutter array (MSA) is a programmable optical spatial filtering device fabricated by micro electro-mechanical system (MEMS) technology. It was originally developed for James Webb Space Telescope (JWST) to enable multi-object spectroscopy and operated by a moving magnet. Next ... 詳細を見る

HVDC electrodes are installed on HVDC transmission systems to provide a low resistance current return path during both monopolar and bipolar operation, using the earth and/or sea as the conductive medium. HVDC electrodes are in general less costly and have lower losses than dedicated ... 詳細を見る

This study investigates the effect of a uniform magnetic field on the lateral migration behavior of a ferrofluid droplet in a plane Poiseuille flow at arbitrary directions by means of numerical simulation. A numerical scheme called level set method in combination with the laminar two ... 詳細を見る
