Integration of surface acoustic wave (SAW) devices with nanostructures has gained interest in the development of sensors with high sensitivity. To better design nanostructure integrated SAW devices, it is essential to model three dimensional (3-D) SAW devices and analyze the wave propagation characteristics in nanostructure-enhanced SAW devices. In this work, a 3-D finite element model of ...

The interface between microelectrodes and biological tissue is of great interest to researchers working on extracellular stimulation. In this paper, we outline a method used to model the complex double layer capacitance at the interface between the electrodes and the cortex. This model relies on the combined power of SPICE, MATLAB, and COMSOL Multiphysics. The goal of this model is to ...

A finite-element model of wave propagation using COMSOL Multiphysics has been developed to solve the problem of ultrasound scattering from spherical structures. This model will be used to predict ultrasound backscatter from cells for ultrasound tissue characterization, and scattering from microbubble contrast agents. In this paper, we discuss an improvement to our model by using a ...

In this work a micro-cantilever optical-MEMS sensor based on the AlGaAs system is designed and modeled. The device consists of two micro-cantilever beams perfectly aligned with the free ends separated by approximately 200 nm up to 2000 nm. The finite element method (FEM) (COMSOL Multiphysics) has been employed here to model the structural deformation and light propagation through the device. ...

The impedance based biosensor utilizes the electrical impedance measurements between interdigitated electrodes integrated into a microchannel containing the target cells in a suspension medium. The detection is based on measuring the change in impedance caused by the presence of bacteria. In this paper we describe the simulation of impedance measurements using the electromagnetics module of ...
This paper discusses the impact and modeling of stress experienced during the silicon fabrication process for Mosfets. The work addresses some of the issues that come up while trying to model the impact strain has on device performance. Strain dependent mobility models are also discussed.

This work is focused on the coupling of a Monte Carlo code with COMSOL Multiphysics conduction/convection, and electrostatic modules in solving fluid-Poisson model for the plasma properties for a practical DC magnetron low pressure plasma discharge. The magnetostatic module was used in calculating the required magnetic field.

A model has been designed and constructed for the all-liquid, sodium borohydride/hydrogen peroxide fuel cell. The electrochemical behavior, momentum balance, and mass balance effects within the fuel cell are modeled using the Butler-Volmer equations, Darcy’s law, and Fick’s law, respectively within COMSOL Mutiphysics. The simulations performed with the model indicate that an optimal ...

The main focus of this paper is the modeling, simulation, and analysis of the CaBr2 hydrolysis reactor stage in the Calcium-Bromine thermochemical water splitting cycle for nuclear hydrogen production. One concept is to use a spray reactor of CaBr2 into steam. Given the large heat reservoir contained in a pool of liquid CaBr2 that allows bubbles to rise easily, using a bubble column for the ...
