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.

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.
