The demand for phased array antennas increases not only for the traditional military industry but also in commercial areas such 5G mobile network platforms, Internet of Things (IoT), and satellite communication applications. This example shows how to design a phased array with a beam ... 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
The models here showcase several use cases of the Circuit Extractor add-in, which is able to generate electric circuits from solved physics. A more detailed description of this tutorial model can be found in the blog post "Extracting Electrical Circuits from Electromagnetics ... En savoir plus
This tutorial demonstrate the use of a Cross Grating feature in an échelle spectrograph. A cross grating is a periodic surface with two directions of periodicity. In this model the cross grating is used in high order in one direction and in first order in the orthogonal ("cross") ... En savoir plus
A magnetic brake consists of a permanent magnet, which induces currents in a rotating copper disk. The resulting eddy currents interact with the magnetic flux to produce Lorentz forces and subsequently a braking torque. This 3D problem is solved using a stationary formulation for the ...

This example model calculates the bistatic radar cross section (RCS) per unit length of a circle using the Electromagnetic Waves, Time Explicit physics interface. A 2D circle is excited by a 200 MHz sinusoidal signal modulated by a temporal Gaussian pulse. A wideband RCS frequency ... En savoir plus
Wave heated discharges may be very simple, where a plane wave is guided into a reactor using a waveguide, or very complicated as in the case with ECR (electron cyclotron resonance) reactors. In this example, a wave is launched into reactor and an Argon plasma is created. The wave is ... En savoir plus
Compact camera modules are widely used in electronic devices such as mobile phones and tablet computers. In order to reduce both the size and number of elements required the optical design will typically incorporate several highly aspheric surfaces. This model demonstrates a five element ...
