INTRODUCTION: Nuclear magnetic resonance (NMR) spectroscopy is a broadly used research technique that exploits the magnetic properties of atomic nuclei with non-zero spin in order to determine the physical/chemical properties of the molecules in which they are contained. However, NMR has fundamental sensitivity limitations, as a consequence of the small energy difference between nuclear spin ...

For the design of an inductive power and data transfer electromagnetic calculation are carried out. A transfer system is considered for loads that are distributed across some distances. For example, such loads are adjustable speed drives that are found in factory automation and intra-logistic. Physical properties of the inductive transfer are modeled via COMSOL. Lumped parameters are deduced ...

The present work deals with dynamic simulation of magnetic particles present in the carrier fluid when subjected to external magnetic field. Magneto rheological fluid comes under classification of smart materials, which contain pure CI iron particles, silicon oil as carrier fluid and additives. The yield stress of the magneto rheological fluid can be controlled by varying the external magnetic ...

The filling process of thermoformed cups with food like yogurt is followed by placing a laminated aluminum foil for hermetic sealing on top of the cup. By today’s standards the sealing of the thermoformed aluminum foil with the cup is primarily realized by contact heat with a hot stamp. However this method has tremendous disadvantages. The hot stamp may locally cause a detachment of the color ...

The field quality requirements of most particle accelerator magnets are very tight and, therefore, very precise simulations are needed to accurately calculate these devices. CERN\'s ROXIE code is widely used as a reference software to calculate normal conducting and superconducting magnets for particle accelerator applications. ROXIE uses the full vector potential coupled to the BEM-FEM ...

The radiation force effects on the surface displacement can be calculated by solving the Navier-Stokes equation with appropriated boundary conditions. The surface deformation can be described by the radiation pressure as well as those forces due to gravity and surface tension. We used the photomechanical mirror (PM) method to measure the time-evolution of the nanometer deformation generated on ...

A model of a cell counter sensor based on Impedance Spectroscopy (IS) has been implemented in COMSOL Multiphysics. The cell counter is a silicon-based microdevice consisting in 3D electrodes placed in a wide microchannel: cells flow in the microchannel through the electrodes to be detected. The model allows to evaluate the functionality of the device depending on geometrical parameters and ...

The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL Multiphysics® to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate the modeling of open four and five conductors systems. We successfully demonstrated the calculation of the ...
