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?

Building a Magnetohydrodynamic Multiphysics Model in COMSOL®

June 19, 2019

Magnetohydrodynamic models call for fluid dynamics and electromagnetics couplings. To do so, you can set up bidirectional couplings between all physics equations or building a simplified model.

How to Use Circular Ports in the RF Module

May 10, 2019

Degeneracy in circular ports leads to uncertainty in the mode field orientation. Not so with the Circular Port Reference Axis feature, which lets you define field orientations on port boundaries.

Speeding Up DNA Separation in a Microchannel via Simulation

May 9, 2019

DNA separation takes a long time using traditional methods. Now, researchers from the Missouri University of Science and Technology have found a faster way to get the job done.

How to Numerically Simplify Your Periodic RF Models

April 22, 2019

Looking for an easier way to model periodic RF structures, such as frequency selective surfaces, electromagnetic band gap structures, reactive and high impedance surfaces, and metamaterials?

Your Guide to the Physics Interfaces and Studies in the RF Module

April 19, 2019

The RF Module includes 4 physics interfaces and studies that you can use to analyze electromagnetic wave propagation and resonance behavior in your RF analyses.

Your Guide to Lumped Ports in the RF Module

April 12, 2019

Your guide to the 4 different types of lumped ports that you can use for your RF analyses, as well as the different modeling scenarios in which each type is applicable.

Fine-Tuning the Design of Piezoelectric Transducers with Simulation

April 5, 2019

A variety of use cases and a variety of physics: Piezoelectric transducer designs need to account for electric currents, pressure acoustics, stress-strain, and acoustic-structure interaction.
