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 newly emerging field of carbon-based MEMS (C-MEMS) attempts to utilize the diverse properties of carbon to push the performance of MEMS devices beyond what is currently achievable. Our design employs a carbon-carbon composite using nano-materials to build a new class of MEMS accelerometer that is hyper-sensitive over a dynamic range from micro-G to hundreds of G’s – far surpassing the ...

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 ...

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 ...

Nanoparticles are being extensively researched as a noninvasive method for selectively targeting and killing cancer cells. In this study, we model the thermal activation of gold nanospheres and nanorods in a fluidic environment to determine the thermal response of the surrounding medium.

In this study, a detailed finite element model coupling the motion dynamics and electromagnetics of a diaphragm based MEMS vibration energy harvester is presented. The energy harvester converts low frequency vibrations to high frequency response by magnetic actuation of a diaphragm carrying coils. AC/DC, Solid Mechanics and Moving Mesh (ALE) modules are coupled together in one 3-D model to ...

In this work we have constructed a 2D COMSOL model for the drying of Latex. It is based on a prior 1D model of Kiil, but also includes the effects of a flowing air stream, which is necessary to remove the evaporated water vapor. The model illustrates several features of drying that are not accessible to the 1D model, in particular the a profile in the air/water interface that forms near the ...

Electroplating is a vital technology widely employed for many technological applications ranging from decorative or anti-corrosion coatings to high precision nanotechnology passive electromagnetic cloaking devices. This 2D Axisymmetric Electroplating Model demonstrates one of the modeling methodologies that can be used to calculate the transient generation of a coating thickness of a ...
Numerical Study of the Effect of Fins on the Natural Convection Driven Melting of Phase Change Material
C. Liu, and D. Groulx
Natural convection has to be accounted and simulated for in order to properly describe the physics encounter in the phase change process. A simplified two-dimensional model was created in COMSOL 4.1. Natural convection was accounted for by adding a volume force and using the Boussinesq approach. The heat transfer and laminar flow physics were used. Results showed that natural convection ...
