Investigating Magnetic Field Exposure Near Transmission Lines
Electromagnetics simulation can be used to predict and investigate magnetic field exposure around power transmission lines and other electrical infrastructure.
5 W’s for 200 Years of Electromagnetism
Fun fact: Hans Christian Ørsted originally studied pharmacology and philosophy before he went on to discover the connection between electricity and magnetism.
k • p Method for Strained Wurtzite GaN Band Structure
Model a wide range of semiconductor systems, such as particles with spins and strained wurtzite crystals, using multicomponent wave function functionality in the Schrödinger Equation interface.
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.
