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?

Modeling Metallic Objects in Wave Electromagnetics Problems
What is a metal, anyway? These materials are highly conductive and very good at reflecting incident electromagnetic waves, including light, microwaves, and radio waves.
Ports and Lumped Ports for Wave Electromagnetics Problems
The Lumped Port boundary condition can be used to model boundaries through which a propagating electromagnetic wave will pass without reflection. Learn how to use this feature in your EM models.
Optimizing Mach-Zehnder Modulator Designs with COMSOL Software
3 design requirements for a Mach–Zehnder modulator: It must produce low loss, give a 50/50 split of power through the 2 output arms, and be used as a spatial switch. See how simulation can help.
Benchmark Model Results Agree with Fresnel Equations
Bright idea: When a ray of light (an electromagnetic wave) propagating through free space hits a dielectric medium, part of the light will be transmitted and part will be reflected.
Modeling Electromagnetic Waves and Periodic Structures
Oftentimes, it is of interest to model an EM wave (light, microwaves) incident upon periodic structures, such as diffraction gratings, metamaterials, and frequency selective surfaces.
Gaussian Beam Striking an Array of Nanorods
A Gaussian beam that is striking an array of nanorods is an example of optical scattering. Consider metallic nanorods that are very close together and have a diameter much smaller than the wavelength of a Gaussian beam that falls upon them. If the beam were to be polarized along the rods, they would act as though they were not actually individual rods, but a sheet of metal. The array is nearly transparent to the wave when it is polarized perpendicular […]
Taking Care of Fast Oscillations with the Wave Optics Module
The new COMSOL Multiphysics Wave Optics Module provides engineers with a great set of features for designing their simulations. One of the new capabilities included in this module is the groundbreaking beam envelope method for electromagnetic full-wave propagation. We hope this feature will become instrumental to the optics community.
