Zeiss, Abbe, and the Evolution of Microscopes and Optical Research

September 11, 2019

The story of Carl Zeiss and Ernst Abbe involves a picturesque town in Germany, compound microscopes, and a hammer and anvil. See for yourself with a glimpse into the history of optical research.

How to Produce 3D Far-Field Plots from 2D Axisymmetric RF Models

August 8, 2019

When modeling certain resonant structures, you can get the best of both worlds: 2D axisymmetry offers efficient computations while 3D far-field plots are available for postprocessing results.

Samsung Amps Up Loudspeaker Designs with Simulation

July 29, 2019

Some organizations reach success and then shift the goal post. Take Samsung, for instance: Although they lead the market for televisions and smartphones, they set their eyes on another goal…

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?
