Designing Inductors with a Simulation App at Bombardier Transportation
Every day, 500 million passengers in 200 cities and 60 countries ride a train featuring Bombardier Transportation products. See how apps help speed up the design process for a train component…
Modeling a Pierce Electron Gun in COMSOL Multiphysics®
Cathode ray tubes, electron microscopes, spectrometers, and particle accelerators: These devices and components commonly use Pierce electron guns.
Model Vortex Lattice Formation in a Bose–Einstein Condensate
Bose–Einstein condensation can cause superfluidity, superconductivity, lasers, and trapped dilute cold atoms. When such systems are subjected to rotating perturbation, it forms a vortex lattice.
It’s a Bird, It’s a Plane, It’s…Gravity-Defying Spiders!
Spider ballooning, in which spiders float for miles, was originally observed by Charles Darwin in 1832. Since then, researchers from University of Bristol used simulation to study this effect.
3 Examples of Modeling Transitions for Rectangular Waveguides
Waveguide to planar, coaxial to waveguide, and rectangular to elliptical: These 3 different transitions for rectangular waveguides can be modeled using COMSOL Multiphysics® and the RF Module.
Course: Modeling Joule Heating with Thermal Expansion
Get an overview of the course on Joule heating and thermal expansion. Plus, access supporting material.
How Does This Lip Gloss Appear to Defy Gravity?
We attempt to explain a mysterious, gravity-defying phenomenon involving a viral video, dielectric materials, electrostatics, and lip gloss.
Modeling a Scatterer Near an Optical Waveguide
In the real world, most structures are more complex than a 2D dielectric slab. However, if you’re designing photonic structures, you can learn a lot about wave optics modeling from this example.
