This model simulates an LED that emits in the infrared part of the electromagnetic spectrum. The device structure is made up of a single p-n junction formed by a layer of p-type doping near the top surface of an otherwise n-type wafer. This kind of device geometry is simple and cheap to ...

Bearings are used in machines to reduce the friction between moving parts and thereby smooth their relative motion. Rolling element bearings are one of the most widely used bearings, where rolling elements or rollers are used to support the load. These rollers can be of different shapes; ... En savoir plus
This example models the desalination of water by capacitive deionization in a "flow-between" cell (fbCDI). The model geometry is in 2D. Steady Brinkman flow, a tertiary current distribution, and the improved modified Donnan description of the deionization process is assumed. En savoir plus
When analyzing rotors, it is common that bearings are modeled through their effective dynamic coefficients about a static equilibrium position. This model illustrates how to compute such coefficients for a cylindrical journal bearing. The bearing length is kept much smaller than its ... En savoir plus
A Czerny-Turner monochromator spatially separates polychromatic light into a series of monochromatic rays. This model simulates a crossed Czerny-Turner configuration that consists of a spherical collimating mirror, a planar diffraction grating, a spherical imaging mirror, and an array ... En savoir plus
In his example, the lowest natural frequency of a 3D bracket are maximized using shape optimization. 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
In this example, a rotor supported on two hydrodynamic bearings is analyzed. An eccentric disk located between the two bearings causes the rotor to whirl. One of the bearings is misaligned with the axis of the rotor. The Beam Rotor with Hydrodynamic Bearing interface in the ... En savoir plus
This model illustrates how to compute the torque of a three-phase squirrel-cage induction motor at various speeds. In the example the torque is computed by averaging the results from simulations performed on 2D cross sections at several locations along the induction motor. The 3D ... En savoir plus
In this model, we introduce a cloaking method using an electrically tuned monolayer of graphene. We will show that when a cylindrical dielectric scatterer is covered in graphene, the scattering cross section is greatly reduced at the designated frequency, making it electromagnetically ...
