Modeling of Materials in Wave Electromagnetics Problems

May 27, 2015

Get an introduction to the various material models that are relevant to modeling wave electromagnetics problems in COMSOL Multiphysics®.

Modeling Metallic Objects in Wave Electromagnetics Problems

May 14, 2015

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

March 9, 2015

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.

Using Perfectly Matched Layers and Scattering Boundary Conditions for Wave Electromagnetics Problems

January 28, 2015

Learn how to use scattering boundary conditions and perfectly matched layers to truncate domains for your wave electromagnetics problem — and which technique is best for your modeling scenario.

Optimizing Mach-Zehnder Modulator Designs with COMSOL Software

April 8, 2014

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

March 12, 2014

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

January 17, 2014

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.

Visualization for 2D Axisymmetric Electromagnetics Models

December 31, 2013

Today we’ll look at how to make 3D plots of vector fields that are computed using the 2D axisymmetric formulation found in the Electromagnetic Waves, Frequency Domain interface within the RF and Wave Optics modules.
