In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... En savoir plus
Indentation tests are commonly used to evaluate the safety of battery cells by assessing the risk of internal short circuits under external mechanical loads. This example demonstrates how to set up such a test, in which an indenter is pressed onto a battery cell, causing large ... En savoir plus
This model illustrates the process of evaluating the radar cross section (RCS) of a metallic sphere through the utilization of the boundary element method (BEM). By taking advantage of a vertical symmetry plane that is parallel to the polarization of an incident background field, the ... En savoir plus
Electronic equipment often has to be certified to function after having been subjected to a specified shock load. In this example, the effect of an 50g 11ms half sine shock on a circuit board is investigated using response spectrum analysis. The results are compared with a time domain ... En savoir plus
This example shows the modeling of a resin transfer molding (RTM) process for a wind turbine blade using the Two-Phase Flow, Level Set, Brinkman Equations interface. Resin is injected into a preform consisting of different composites with different anisotropic permeabilities. En savoir plus
An eigenfrequency study is used to find the resonance frequency and threshold gain for an oxide-confined, GaAs-based, vertical-cavity surface-emitting laser (VCSEL). The simulations are performed in two steps. A regular eigenfrequency analysis is first performed, to find good initial ... En savoir plus
Light rail transit (LRT) systems often utilize DC power for train propulsion. In these systems the potential gradients in the rails may induce stray currents, which corrode adjacent metallic structures. In this example, the Cathodic Protection interface, using Edge Electrode nodes, is ... En savoir plus
An established method for benchmarking the atmospheric corrosion resistance of materials is the use of accelerated corrosion tests (ACT) performed in climate chambers. The main purpose of the ACTs is to make reliable and fast predictions of the long time behavior. The tests expose ... En savoir plus
This model demonstrates how to perform simulations of an absorbing bandstop color filter, based on a hexagonal array of holes in a thin aluminum layer. The structure is hexagonally periodic but this example also shows how to set the model up as rectangularly periodic. En savoir plus
Planar photonic waveguides in silica (SiO2) have great potential for use in wavelength routing applications. The major problem with this type of waveguide is birefringence. Anisotropic refractive indices result in fundamental mode splitting and pulse broadening. The goal is to minimize ... En savoir plus
