COMSOL® Simulation for Scanning Microwave Microscopic Experiments

T. Le Quang [1], D. Vasyukov [1], A. Buchter [1], J. Hoffmann [1], M. Zeier [1],
[1] Eidgenössisches Institut für Metrologie (METAS), Switzerland

In the EMPIR project ADVENT the Scanning Microwave Microscopy (SMM) is investigated. The SMM is a still rather novel member of the family of scanning probe microscope. It has attracted a lot of attention recently, because this instrument can be used to characterize various electrical ... En savoir plus

Steady-State and Transient Electrothermal Simulation of Microheater for Gas Sensing

A. N. Radwan [1], M. Mehregany [1],
[1] Case Western Reserve University, Cleveland, OH, USA

Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ...

[1]Prairie View A&M University, Prairie View, TX, USA
[2]Indiana University-Purdue University, Fort Wayne, IN, USA

This paper presents an analysis approach of multicondcutor quasi-TEM lines transmission interconnect in a single dielectric region and multimode waveguides using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in ... En savoir plus

Using COMSOL Multiphysics in Eddy Current Non Destructive Testing Context

L. Santandrea, and Y. Le Bihan
Laboratoire de Génie Electrique de Paris, Gif-sur-Yvette, France

Eddy current testing (ECT) is widely used to check the integrity of electrically conducting parts and notably to detect flaws. It is based on the interaction between a probe and the part under testing. The finite element method (FEM) is well fitted to the modelling of these kinds of ... En savoir plus

Simulation of Microwave Heating of Porous Media Coupled with Heat, Mass and Momentum Transfer

J. Subbiah[1], J. Chen[1], K. Pitchai[1], S. Birla[1], D. Jones[1]
[1]University of Nebraska, Lincoln, NE, USA

A microwave heating model coupled with heat, mass, and momentum transfer is needed to fully understand the microwave heating process. In this study a comprehensive 3D model was developed for studying the interaction of microwave with the food. The model includes physics of Maxwell’s ... En savoir plus
