App: Measuring the Diffraction Efficiency of a Wire Grating
We go over the features of the Plasmonic Wire Grating Analyzer demo app, which you can use as inspiration to build your own apps for more efficient wave optics and photonics simulation.

Should We Model Graphene as a 2D Sheet or Thin 3D Volume?
Graphene is a 2D sheet of carbon atoms that is 1 atomic layer thick. However, is graphene actually 2D or is it just incredibly thin, like a very fine piece of paper? How should it be modeled?

Simulating a Transparent Light Pipe to Optimize Transmittance
Transparent light pipes are used as an optimal source of natural light for underground areas, like subway stations, and areas without a lot of natural light, like prisons.

How to Model Magnetic Bearings in COMSOL Multiphysics®
Get an in-depth introduction to the different types of magnetic bearings and then learn how to compute their magnetic force, torque, magnetic stiffness, and more.

How to Adapt the Real World for Electromagnetics Simulations
Using an example of a biconical antenna in an anechoic chamber, we discuss how to closely mimic the conditions of real-world environments in your electromagnetics simulations.

Guide to Frequency Domain Wave Electromagnetics Modeling
Read this blog post for your introduction to the various types of problems that you can solve in the RF and Wave Optics modules with COMSOL Multiphysics®.

Optimizing Antenna Design for 5G and the Internet of Things
By optimizing the performance of existing mobile device antennas, we can ensure that new technology and devices are ready to operate under the 5G mobile network and internet of things.

Modeling Laser-Material Interactions in COMSOL Multiphysics
