Silicon micromechanical resonators have long been used for designing sensors and are now becoming increasingly important as oscillators in the consumer electronics market. In this series of models, a surface micromachined MEMS resonator, designed as part of a micromechanical filter, is ... En savoir plus
Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ... En savoir plus
This tutorial demonstrates the use of the density-gradient formulation to include the effect of quantum confinement in the device physics simulation of a silicon inversion layer. This formulation requires only a moderate increase of computational resources as compared to the conventional ... En savoir plus
This single-phase induction motor model is used to compare with Testing Electromagnetic Analysis Method (TEAM) workshop problem 30. The Magnetic Fields physics interface is used to model the motor in the frequency domain at 60 Hz. The Velocity (Lorentz Term) feature is used to model the ... En savoir plus
An electrodynamic ion funnel provides an efficient means of transferring ions from regions of high pressure to high vacuum. The ion funnel can couple devices which generally operate at pressures of different orders of magnitude, such as ion mobility spectrometers and mass spectrometers, ... En savoir plus
A magnet moving axially through the center of a coil will induce a voltage across the coil terminals. One practical application of this is in shaker flashlights, where the flashlight is vigorously shaken back and forth, causing a magnet to move through a multi-turn coil, which provides ...

Several different approaches to optimizing a ten-turn axisymmetric coil are presented. First, the current in each turn is adjusted with the objective of having a uniform magnetic flux density along the centerline. Second, the currents are adjusted to minimize power dissipation with a ... En savoir plus
This model shows how to model an electrolyte-gated organic field-effect transistor based on a general drift-diffusion model. The model uses the Stabilized Convection-Diffusion Equation interface and the Electrostatics interface. The transistor characteristics are visualized. Formation of ... En savoir plus
Thermoelectric elements are often used to cool or heat electronic components to a desired temperature. In such simulations, you are typically not interested in the behavior of the thermoelectric element itself but want to use its performance characteristics to model the overall response ...
