In the last decade, the surface plasmon resonance (SPR) has become a very sensitive technique for real-time detection in many application areas. Considering the fiber optic concept and the important needs for analyzing biomolecular reactions through automated and miniaturized components, fiber optic sensors based on the SPR technique are becoming an important choice in the field of sensing. In ...
The developments of microsystems for biotechnology have been fast in the last few years, and no sign of slowing down is observed. It has begun with lab-on-chip for genomics, especially for the recognition of DNA sequences, followed by protein reactors and immunoassays, and today the emphasis is on cellomics. Cell-chips are design to monitor the behavior of cells, individually or as a group, ...

The purpose of this paper is to present a numerical modeling of plasma phenomena in beryllium emissions using COMSOL Multiphysics software. The Beryllium films were deposited on mirror polished fine grain graphite substrates using the Thermionic Vacuum Arc (TVA) technology available at NILPRP – Magurele, Romania. The developed system for thin film deposition using thermionic vacuum arc (TVA) ...

In semiconductor gas sensors, the base of the gas detection is the interaction of the gaseous species at the surface of the semiconducting sensitive material. Since the chemical reactions at the surface of the sensor material are functions of temperature. We simulate our µHeater design on a Buckled Cantilever Plate (BCP). Such structure allows the sensor to be suspended for thermal insulation. ...

A human torso model was created for heat transfer analysis. The torso was derived from the ‘Virtual Family’ whole-body voxel data from the ITIS Foundation (Zurich, Switzerland). Measurements were taken from the ITIS male along the axial plane at key anatomical landmarks and used to develop geometry in Solidworks. Individual components were created to represent the skin, fat, muscle, and bone ...

COMSOL Multiphysics is used to simulate natural convection and its impact on peak operating temperatures of solid-sate lighting in thermally adverse conditions. PDE modes in the general form are used in conjunction with a thin-surface conduction formulation in the weak form. COMSOL is used to predict both temperatures and heat flows through numerous components of the configuration. Model ...

An alluvial aquifer system has probably conceived as a numerical modeling hell. We have chosen COMSOL Multiphysics® for two reasons: 1) FEM methods allow to use complex geometries; 2) multiphysics simulation permits to run a single model with all phenomena. We built a section with these physics: a) Darcy's law, b) Richards' equation, c) ALE to show surface deformation, d) Hydrogeologcal ...

Multiphysics Simulation of Polymer-Based Filters for Sub-Millimeter Space Optics This work focuses its analysis on polymer-based filters used in space-borne astronomical instrumentation for Cosmic Microwave Background Radiation and Far-Infrared observations. Most of these observatories mount quasi-optical elements made of such materials, due to their high transparency and low absorption in ...

The approach of this project is Modeling a Coriolis Mass Flow-meter (CMF) bases on a Fluid-Structure Interaction (FSI) device. The "Coriolis mass flow-meter sensor" is modeled using COMSOL Multiphisics® simulation, the Acoustic-Shell Interaction physics interface and coupled by FSI physics interface to drive and simulate the sensor. The modeling and simulation are provided into two different ...
