Computational Electromagnetics Modeling: Which Module to Use?
If you work with a particular electromagnetic device or application area, you might be wondering which module in the COMSOL product suite is right for you. Keep reading for a comprehensive intro.
Zeiss, Abbe, and the Evolution of Microscopes and Optical Research
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.
Studying the Polarization of Light with a Fresnel Rhomb Simulation
A Fresnel rhomb is a simple optical system for studying light polarization. Follow along as we simulate linearly, elliptically, and circularly polarized incident light in a Fresnel rhomb.
