New Piezoelectric Modeling Interface in COMSOL 5.0

December 30, 2014

As of version 5.0 of COMSOL Multiphysics®, there is a new interface for simulating piezoelectric devices; it has predefined features that make it easy to set up and run a piezoelectric model.

Ray Tracing in Monochromators and Spectrometers

December 25, 2014

Spectrometers are optical devices that measure some property of radiation as a function of its frequency, while monochromators transmit radiation of a specific frequency.

Modeling a Surface Micromachined Accelerometer

December 23, 2014

There are plenty of MEMS manufacturing techniques, but surface micromachining is preferred because it can merge electronic components and freely moving mechanical parts onto one substrate.

Fillet Away Your Electromagnetic Field Singularities

December 18, 2014

Did you know that you can use fillets and chamfers in your electromagnetics models to avoid electromagnetic field singularities? Learn how in this tutorial blog post.

Modeling Beam Neutralization with a Charge Exchange Cell

December 16, 2014

A charge exchange cell refers to an area of high-density gas that is placed in the path of an ion beam. You can model a charge exchange cell to analyze its neutralization efficiency.

An Analysis of Caustic Surface Generation at the Vdara® Hotel

December 12, 2014

The Vdara® hotel on the Las Vegas strip has a unique crescent-shaped design that unfortunately contributed to the development of a caustic surface on the hotel’s pool deck.

Automatic Meshing for Electromagnetic Simulations

December 9, 2014

Ever struggle to mesh the infinite elements or perfectly matched layers in your electromagnetics simulations? Automatic meshing can help >>

Modeling Ray Propagation in a Newtonian Telescope System

December 5, 2014

Ray optics trivia: The Newtonian telescope, recognized as the earliest operating reflecting telescope, was developed in 1668. Today, simulation can be used to trace rays through this device.
