This model demonstrates the use of boundary element method in the Electromagnetic Waves, Boundary Element interface to model an optical Yagi-Uda antenna. The antenna is driven by an electrical point dipole, which is implemented through the background field. The field distribution around ... Mehr lesen
In the semiconductor industry, rapid thermal annealing (RTA) is a semiconductor process step used for the activation of dopants and the interfacial reaction of metal contacts. In principle, the operation involves rapid heating of a wafer from ambient to approximately 1000–1500 K. As soon ... Mehr lesen
SMA connectors are popularly used on printed circuit boards (PCB) for testing. This model shows how to excite an SMA connector on a microwave substrate and how to terminate a grounded coplanar waveguide (GCPW) with 50 ohm using a lumped port and an air-bridge. Mehr lesen
Die Ersatzmodell-App Thermischer Aktuator zeigt, wie Sie die Berechnung für Multiphysik-Analysen mithilfe eines Ersatzmodells beschleunigen können. Ein Ersatzmodell ist ein einfacheres, in der Regel rechnerisch günstigeres Modell, das zur Annäherung an das Verhalten eines komplexeren und ... Mehr lesen
Just like optical lenses focus light, electric and magnetic lenses can be used for focusing beams of charged particles. This COMSOL Multiphysics model shows the path of B5+ ions passing through a focusing system of three magnetic quadrupoles. Each of the quadropoles focus the beam of ... Mehr lesen
In this tutorial example, the concepts of Component Mode Synthesis (CMS) are introduced through a simple solid model of a cantilever beam. Parts of the beam are reduced by the CMS technique. It is, furthermore, shown how CMS can be used to represent both the static and dynamic behavior ... Mehr lesen
Patch antennas are becoming more common in wireless equipment, like wireless LAN access points, cellular phones, and GPS handheld devices. The antennas are small in size and can be manufactured with simple and cost-effective techniques. Due to the complicated relationship between the ... Mehr lesen
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... Mehr lesen
This application presents an example of pressure driven flow and electrophoresis in a 3D micro channel system. Researchers often use a device similar to the one in this model as an electrokinetic sample injector in biochips to obtain well-defined sample volumes of dissociated acids and ... Mehr lesen
The catenary is the geometrical shape that corresponds to the curve followed by an idealized chain or cable supported at both ends and hanging under its own weight. The viscous catenary problem describes the motion of a cylinder of highly viscous fluid, supported at its ends as it flows ... Mehr lesen
