Understanding the rock structure at nano to micro scale is of growing importance in geology, oil and gas, and hydrology. New approaches that relies on a variety of high resolution 3D imaging techniques offered tremendous potential. These new approaches, in the meanwhile, introduce significant new challenges. Starting from digital imaging data, the paper introduces an image-to-simulation ...

Microwave imaging has been recently proposed as a potentially useful screening technique for breast cancer. This method detects abnormalities in the tissue based on permittivity difference between breast normal and malignant tissue. In this method breast is illuminated by high frequency electromagnetic wave, and received waves are then analyzed in order to construct a map of breast\'s ...

A biconcave-shaped Red Blood Cell was trapped and deformed in a dual-trap optical tweezers. The two highly focused trapping beams of Gaussian intensity distribution were modeled as background field in the COMSOL Radio Frequency Module. The 3D radiation stress distribution on the cell surface was computed via the Maxwell stress tensor. The 3D deformation of the cell was computed with the ...

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 ...

This paper concerns the problem of obtaining proper acoustic attenuation performance through computations. COMSOL was used to solve acoustics systems with helicoidal resonators in the frequency domain. Based on the studies of insertion and transmission loss of helicoidal resonators, a high consistency between the results obtained by numerical calculations with experimental measurements was ...

Petroleum reservoir simulation is a process of modeling the complex physical phenomena inside a reservoir. This study presents an application of an analytical based numerical scheme so called the Boundary Element Method (DRBEM). It is proven to be able to provide a computationally efficient means of handling single and multiphase flow in a homogeneous medium through the comparison study with ...

The silicon substrate has a significant effect on the inductance parameter of a lossy interconnect line on an integrated circuit. It is essential to take this into account in determining the transmission line electrical parameters. In this paper, a new quasi-TEM capacitance and inductance analysis of multiconductor multilayer interconnects is successfully demonstrated using the finite element ...

Patch antennas are widely used in communications links with unmanned aerial vehicles. Their hemispherical send and receive patterns enable the systems to maintain radio frequency contact over a wide range of vehicular attitudes. A microstrip-fed design offers other attractive features including lightweight, inexpensive, and a 3-D structure that can be easily integrated into the fuselage. This ...

The Delmarva Peninsula is located on the East Coast of the United States, between the Chesapeake Bay and Atlantic Ocean. Industrial farming in the Delmarva Peninsula leads to levels of nutrients nitrogen, which grossly exceed natural levels and greatly impair the health of the bay. The main source of water carrying excess nitrogen to streams is groundwater. We use the software package COMSOL ...

Susceptors are very thin metallic microwave absorbing films used in microwaveable food packaging. They tend to heat up very rapidly during microwave heating and this effect helps to overcome two major issues faced in domestic microwave ovens; 1) Non-uniform heating and 2) lack of browning. While susceptors are being widely used, there is still a lack of scientific knowledge about their ...
