Digital microfluidic system based on EWOD (electrowetting-on-dielectric) technology can perform different fluidic operations on the same electrode array by simply modifying control software. One of the major challenges in EWOD device is to address each electrode individually in M x N array of electrode using simple fabrication architecture without compromising in system performance. The ...

Curved cone corrugated ground plane conical antenna has been designed and analyzed using Finite Element Method. In this paper, we introduce a novel Curved cone corrugated ground plane conical antenna for ultra-wideband (UWB) applications. The antenna is composed of curved cone with narrow corrugation on finite ground plane and fed by a 50? coaxial cable. The designed antenna operates over ...

The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO2 in the gas above the solid surface is less than the decomposition pressure of the CaCO3. As the reaction is endothermic, the conventional process for calcination uses coal firing in rotary kiln with limestone feed to get the desired temperatures. Microwave heating of limestone is proposed ...

A MEMS based Knudsen’s pressure gauge working in the range of 1e-5 mbar to 10 mbar is designed and simulated in COMSOL. The working principle is based on Knudsen’s forces that arise when two plates are held at different temperatures and their separation is comparable to the mean free path of the ambient gas molecules. The forces change the separation between the plates and capacitance between ...

High power Lower-Hybrid RF waves injected at in a Tokamak plasma can strongly modify the edge plasma. This is caused by ponderomotive forces pushing charged particles in an inhomogeneous oscillating electromagnetic field towards weaker field areas. On the Alcator C-Mod Tokamak, edge density profile measurements by means of an X-mode SOL reflectometer were able for the first time to accurately ...

Domestic microwave ovens are notorious for their uneven heating of food materials. This is caused by a varying electromagnetic field whose variation is caused by a number of factors dependent on the oven and the food parameters. Experimental validation of heating would therefore give highly variable results and would be labour, resource and time intensive. Thus modeling of the microwave ...

Electric fields are present in biological systems at multiple spatial and temporal scales. Electroosmotic flow results from the action of electric field on the electrical double layer, formed at the fluid/solid or fluid/membrane interface and characterized by its zeta-potential. For the physiological value of zeta-potential (50 mV) and a single charged protein of average size, electroosmotic ...

The long-term behaviour of the underground excavations is a social and economic challenge particularly in the contexts of post-mining or radioactive waste storage. Numerical modelings are currently used to understand and forecast the complex behaviour of rock mass around the underground cavities. In order to accurately perform these multiphysics modelings at high space and time scales, it is ...

A Computational Fluid Dynamics study has been performed for a Gas Electron Multiplier (GEM) detector of high energy charged particles, currently under development as part of a new tracker of the high luminosity spectrometers in Hall A at Jefferson Lab. By gradual modifications of the geometry simulated in COMSOL, the design of the frame separating two GEM foils has been optimized with the aim ...
