Evanescent Component of the Nonparaxial Gaussian Beam

May 12, 2020

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.

Modeling the Scattering of Light Off of an Object on a Substrate

April 14, 2020

A common modeling scenario in wave electromagnetics: computing the scattering of light off of a structure patterned on top of a uniform dielectric substrate.

How to Perform Lens Simulations Using the Wave Optics Module

February 19, 2020

Lens simulations in wave optics can be difficult to perform, as they usually require a lot of mesh elements. Learn how to sidestep this issue using the functionality of the Wave Optics Module.

What Is the Curl Element (and Why Is It Used)?

December 30, 2019

When solving some electromagnetics problems, the curl element (also called the edge element or vector element) can be used in the finite element method.

Engineering the Flow of Light Using Photonic Crystals

July 25, 2019

Did you know that the discovery of photonic crystals in 1980 came about because of an attempt to reduce the losses in semiconductor lasers in a specific frequency range?

Keynote Video: Improving Synchrotron Light Sources with Applications

December 19, 2018

For synchrotron light sources, brighter is better: RadiaSoft LLC creates and deploys wave optics simulation applications to design improved vacuum chambers for a synchrotron upgrade project.

Calculating the Spectral Properties of an Optical Ring Resonator

August 14, 2018

The effect of a “whispering gallery” can be observed (a similar way) in another field of science entirely: light waves traveling in an optical ring resonator.

The Nonparaxial Gaussian Beam Formula for Simulating Wave Optics

June 26, 2018
