High temperature super conducting (HTS) cables are gaining attentions for their ability to transmit more power compared to their convention counterparts with essentially no resistance and electromagnetic emissions. They are also appropriate for solving the grid congestion problem in the power corridors with their reduced size and weight. But the AC loss that occurs in the HTS cables reduces the ...

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value of its capacitance. The capacitor of the sensor is coupled to the LC resonant network of a passive RFID tag. ...

Introduction: This study aims the optimization and sensitivity analysis of an existing device. A Secondary Ion Mass Spectrometer (SIMS) device is to be equipped with a high power laser in order to increase sputtering speed. The modified device must be capable of handling the increased level of contamination and energy spread of sample ions. Use of COMSOL Multiphysics® software: Transmission ...

In this presentation it is shown how an axially symmetric coil can be simulated in a non-symmetric environment. A rotationally symmetric coil can be simulated by using a 2D model. Doing so the serial equivalent resistance of the coil is obtained among other results. The influence of the environment needs to be simulated with a 3D model. In this model the single wires of the coil are replaced by ...

Charged particle beam manipulation requires magnetic dipoles for steering and quadrupoles for focusing. Conventional magnets are currently used leading to very large and heavy systems. Miniaturization of the optic magnets would enable the development of more affordable systems and potentially portable devices. The Advanced Magnet Lab, Inc. has developed a revolutionary magnet topology and ...

Particle-particle interactions are usually neglected when considering the behaviour of magnetic particle's so called magnetic beads in e.g. a microfluidic device. However, if the particle density exceeds a critical limit, this assumption might not lead to proper results anymore. In this paper the particle-particle interaction of magnetic beads in an external magnetic field will be discussed. It ...

Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. This work presents a robust approach to the design of EM Shielding based on Graphene (Gph) layers. It is a two ...

Due to the complexity of electromagnetic modeling, researchers and scientists always look for development of accurate and fast methods to extract the parameters of electronic interconnects and package structures. In this paper, we illustrate modeling of multiconductor interconnects in multilayered dielectric media using COMSOL Multiphysics and the finite element method. We specifically ...
