Modeling Waveguides that Support Multiple Modes
2 ways you can model a waveguide that supports multiple modes: add a PML that can be used to absorb any modes, or explicitly add ports for each possible mode.
2 Video Discussions on Multiphysics Simulation of Optics and Photonics
John Wallace, senior editor at Laser Focus World, and Chris Boucher, technical product manager at COMSOL, discuss the use of multiphysics simulation in the optics R&D community. Take a look…
Computational Electromagnetics Modeling: Which Module to Use?
If you work with a particular electromagnetic device or application area, you might be wondering which module in the COMSOL product suite is right for you. Keep reading for a comprehensive intro.
Course: Modeling Electromagnetic Coils in COMSOL®
Get an overview of our Learning Center course on modeling coils using COMSOL Multiphysics and the AC/DC Module, from setting up a coil model to analyzing electromagnetic heating and more.
Using 3D Models to Investigate Inductive Effects in a Submarine Cable
It takes a modern desktop computer ~30 minutes to compute a 3D cable model with twisted magnetic armor. Consequently, 3D cable models are replacing empirical models in the power cable industry.
Modeling Cables in COMSOL Multiphysics®: 8-Part Tutorial Series
Your roadmap to modeling cables with the AC/DC Module and COMSOL Multiphysics®: An 8-part tutorial series that starts with the basics and gradually adds complexity and multiple physics.
Modeling Heat Transfer in Thin Layers via Layered Material Technology
We answer some questions you may have about the Layered Material functionality in the COMSOL® software: What does it do? How do you update existing models? How do simulations benefit from it?
Evanescent Component of the Nonparaxial Gaussian Beam
The evanescent component of the nonparaxial Gaussian beam background field is available as a feature in the Wave Optics and RF modules as of COMSOL Multiphysics® version 5.5.
