This model is a benchmark problem from TEAM workshop (problem 15 part I, see https://www.compumag.org/wp/team/). The model simulates the behavior of a coil as it scans a conductive plate containing a defect (a crack). The computed coil parameters, which include change in resistance and ... En savoir plus
This model analyzes the thermal expansion in a MEMS device, such as a microgyroscope, where thermal expansion should be minimized. The device is made from the copper-beryllium alloy UNS C17500 and uses temperature-dependent material properties from the Material Library. The purpose of ... En savoir plus
Electromagnetic waves that are confined to propagate along a surface, such as surface plasmon polaritons (SPPs), are of great research interest due to their potential applications in nanoscale manipulation of light. This model demonstrates how to set up a simulation of the propagation ... En savoir plus

Antenna crosstalk, or co-site interference, is problematic when multiple antennas are used on a single large platform. In this model, the interference between two identical antennas at VHF frequency is studied with an S-parameter analysis of different configurations of a receiving ... En savoir plus
This tutorial example shows how to use the Electric Currents in Shells interface together with Magnetic Field interface to compute the resistance and inductance of a planar PCB coil in the stationary regime. En savoir plus
Bulk Acoustic Wave (BAW) resonators can be used as narrow band filters in radio-frequency applications. The chief advantage compared with traditional ceramic electromagnetic resonators is that BAW resonators, thanks to the acoustic wavelength being much smaller than the electromagnetic ...

Superconducting materials have zero resistivity up to a certain critical current density, above which the resistivity increases rapidly. To model such a material, this example uses the Magnetic Field Formulation physics interface. The model was based on a suggestion by Dr. Roberto ... En savoir plus
Anti-reflective coatings are frequently used in optical systems to reduce the amount of stray light produced when a beam of light crosses from one medium into another medium with a different refractive index. The simplest example of an anti-reflective coating is a quarter-wavelength ... En savoir plus
This model demonstrates how to simulate a metasurface beam deflector that uses anomalous refraction. The structure itself is a repeated array of six posts (so-called meta elements). The periodicity of the individual posts is 500 nm, so the full structure of six posts is 3 um wide. The ... En savoir plus
