CMOS Based Atom Chips for Sensor Applications

Ph. Neuman [1], A. Nemecek [1], C. Koller [2]
[1] Department for Micro-and Nanosystems, University of Applied Sciences Wiener Neustadt, Austria
[2] Department for Micro-and Nanosystems, University of Applied Sciences Wiener Neustadt, Austria, and School of Physics and Astronomy, University of Nottingham, Nottingham, UK

Ultra-cold atomic systems have proven over the last decade to be a excellent platform for the realization of quantum sensors, quantum computation or quantum simulation applications. A special implementation of this technology is the so called atom chip, where the magnetic fields ... En savoir plus

Multiphysical Simulation of Moved Data Cable

M. Raum [1]
[1] Friedrich-Alexander Universität, Erlangen, BY, Germany

In general this thesis is about the effects of mechanical stress on data cables in moved applications. If a data cable is loaded with different kind of forces and used within high frequency applications it is possible, that the geometrical changes may have an impact on the electrical ...

3D-model of an AC/DC Hybrid EHV Transmission Line to Analyze the Electrical Field along Insulators

D. Potkrajac [1], S. Papenheim [1], M. Kizilcay [1]
[1] University of Siegen, Siegen, Germany

To increase the power transfer capacity of existing lines, a transmission system operator in Germany plans to replace an existing 380-kV three-phase AC system into a bipolar HVDC system on the same tower that is called a 'hybrid line'. Due to the proximity of AC transmission systems and ... En savoir plus

Design and Optimization of Power Cable Accessories Using COMSOL Multiphysics®

A. Lewarkar [1], D. Bergsma [1], S. Madhar [2],
[1] E&D Department, Lovink Enertech B.V., Terborg, Netherlands
[2] Electrical Engineering Department, Delft University of Technology, Delft, Netherlands

Power cable manufacturing is limited by the maximum length of cable that can be produced and stored on cable drums. This creates a need or rather an opportunity for a cable accessory, namely 'Cable Joints'. Joints are an impeccable component in the power cable network that necessitate ... En savoir plus

Impact of the Forces due to CLIQ Discharges on the New HL-LHC Beam Screen

M. Morrone [1], C. Garion [1],
[1] CERN, Geneva, Switzerland

In the framework of the high luminosity large hadron collider (HL-LHC) project, important upgrades will take place by 2024 including the installation of new superconducting magnets in which new beam screens will be placed. The beam screen is an octagonally shaped pipe inserted into the ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus
