This example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... En savoir plus

Induction heating ... En savoir plus
These two models show how to set up a magnetohydrodynamics model using either a fully coupled approach, or a one-way coupled approach. A more detailed description of these models can be seen in the blog post "Building a Magnetohydrodynamic Multiphysics Model in COMSOL®". En savoir plus
These examples show how to model a rectangular waveguide for microwaves in 2D and 3D. A single hollow waveguide can conduct two kinds of electromagnetic waves: transversal magnetic (TM) or transversal electric (TE) waves. The models examine a TE wave that has no electric field ... En savoir plus
A planar dielectric slab waveguide demonstrates the principles behind any kind of dielectric waveguide such as a ridge waveguide or a step-index fiber. This model solves for the effective index and fields of a dielectric slab waveguide and compares the solution to analytic results. En savoir plus
Scientists use the SAR (specific absorption rate) to determine the amount of radiation that human tissue absorbs. This measurement is especially important for mobile telephones, which radiate close to the brain. The model studies how a human head absorbs a radiated wave from an antenna ... En savoir plus
Developments in the last decade have made circuit quantum electrodynamics (cQED) the leading architecture for quantum computation. cQED is the solid-state version of cavity QED, which studies the basic light-matter interactions at the quantum level. This model examines one of the main ... En savoir plus
In this example, a random vibration test of electronic equipment is simulated. Three analyses are performed, one for acceleration in each global direction. Accelerations in the components and forces in clamping bolts are evaluated. En savoir plus
The GEC cell was introduced by NIST in order to provide a standardized platform for experimental and modeling studies of discharges in different laboratories. The plasma is sustained via inductive heating. The Reference Cell operates as an inductively-coupled plasma in this model. This ... En savoir plus
This tutorial is intended as a simple example showing how to model piezoelectric devices using the layered shell functionality. Two cases of material orientation are investigated. In the first case, the pole axis is normal to the shell surface, which results in a change in thickness of ... En savoir plus
