Using COMSOL Multiphysics® for Theoretical and Experimental Validation of Critical Properties of Composite Process

A. Häberle [1], P. Fideu [2], A. Herrmann [1],
[1] CTC GmbH, Stade, Lower Saxony, Germany
[2] Airbus Operations GmbH, Hamburg, Hamburg , Germany

During the manufacturing of CFRP components one of the most critical process steps is the vacuum bagging. In this process several layers of material are draped separately over complex part shapes. The specific properties of each material, which are needed for the process (i. e. breather, ... Read More

Green's Function Approach to Efficient 3D Electrostatics of Multi-Scale Problems

C. Roman [1], L. Schmid [1], L. Stolpmann [1], C. Hierold [1],
[1] ETH, Zurich, Switzerland

We present an efficient method to compute efficiently the general solution (Green's Function) of the Poisson Equation in 3D. The method proves its effectiveness when dealing with multi-scale problems in which lower dimensional objects, such as nanotubes or nanowires (1D), are embedded in ... Read More

Electron Trajectories in Scanning Field-Emission Microscopy

H. Cabrera [1],
[1] Swiss Federal Institute of Technology, Zurich, Switzerland

The Scanning Field Emission Microscopy (SFEM) is a novel technology similar to the better known Scanning Tunneling Microscopy (STM). In STM, electrons are exchanged between the outermost atom of a sharp tip and the outermost atom of a target over sub-nanometer distances by means of the ... Read More

Dynamic Simulation of a Coaxial Magnetic Gear Using Global ODE's and the Rotating Machinery, Magnetic Interface

M. Ostroushko [1], W. Zhang [1], W. M. Rucker [1],
[1] Institute of Theory of Electrical Engineering, University of Stuttgart, Stuttgart, Germany

The coaxial magnetic gear is a good alternative to classic mechanical gears. The magnetic gear has high mechanical durability, overload protection and lower noise, than a mechanical gear [1,2]. A static model of a magnetic gear [3,4] is used for simulation of the magnetic fields and ... Read More

Simulation of CMOS Compatible Sensor Structures for Dielectrophoretic Biomolecule Immobilization

H. Matbaechi Ettehad [1], S. Guha [1], C. Wenger [1],
[1] IHP, Frankfurt (Oder), Brandenburg, Germany

The aim of this paper is to optimize with COMSOL Multiphysics® simulation, the design geometry of a near field biosensor which could be used for dielectrophoretic (DEP) immobilization and simultaneous sensing of biomolecules of the order of nanometers to micrometers. COMSOL Multiphysics® ... Read More

Simulation and Visualisation of Shielding Gas Flows During Wire-Arc Additive Manufacture

I. Bitharas [1], A. Moore [1],
[1] Heriot-Watt Univerisity, Edinburgh, UK

One of the challenges associated with the wire-arc additive manufacture (WAAM) of metals is to provide adequate inert gas shielding, not only for the molten pool, but also for the long reactive metal surface that follows it. For Ti-6Al-4V, it has been shown that increased levels of ... Read More

EMC Simulation Using Source Reconstruction

A. Bergqvist [1], P. Jacobsson [1],
[1] Volvo Cars, Gothenburg, Sweden

Electromagnetic compatibility (EMC) is a growing issue in cars due to the increase in electrification of vehicles. Simulations can be useful for predicting issues at an early stage in the development cycle. This includes investigating EM stray fields that various components generate and ... Read More

Modelling Microwave Scattering from Rough Sea Ice Surfaces

X. Xu [1], A. P. Doulgeris [1], F. Melandsø [1], C. Brekke [1],
[1] Department of Physics and Technology, UiT The Arctic University of Norway, Tromsø, Norway

Sea ice is an important indicator for global climatic changes. Synthetic Aperture Radar (SAR) has been extensively used to monitor sea ice due to rough weather conditions in remote Arctic area. To better understand how SAR signal interacts with the sea ice, Electromagnetic Modeling (EM) ... Read More

Considerations Regarding the Design of a Power Ultrasonic Transducer with Flat Rectangular Plate

R. R. Andrés [1], E. Riera [1],
[1] Grupo de Sistemas y Tecnologías Ultrasónicas, ITEFI, CSIC, Madrid, España

There are several industrial applications, like food dehydration, atomization and textile washing among others, that are enhanced by the use of power ultrasonic transducers with flat rectangular plate radiator. These transducers are composed by three main parts, the piezoelectric ... Read More

COMSOL Multiphysics® Simulations to Study Nonlocal Properties of a Au Nanoshell Using Quantum Hydrodynamic Theory

M. Khalid [1], C. Ciracì [1],
[1] Center for Biomolecular Nanotechnologies, Istituto Italiano di Tecnologia, Arnesano, Italy

Quantum Hydrodynamic Theory (QHT) provides an excellent method to study both near-field and far-field properties of multiscale plasmonic systems, especially for systems whose sizes make it computationally prohibitive for the density functional theory approach [1]. The microscopic ... Read More
