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.

Designing Heating Circuits with Multiphysics Simulation
The electronic message boards you see on the highway contain heating circuits. Their design is a truly multiphysics problem involving heat transfer, structural mechanics, and electromagnetics.

Keynote Video: Optimizing Cable Systems via Simulation
The length of cable for a mode of transportation depends on the amount of passengers, so a car uses ~5 km of cable and a cruise ship uses ~5000 km. Learn more about cable system design here.

Optimizing Planar Coils for PCBs with Electromagnetics Simulation
Planar coils are found in the PCBs of blood pressure sensors, RFID tags, induction cooktops, and more. Use layered shell technology to design optimized planar PCB coils, no matter the use case.

How to Simulate the Carrier Dynamics in Semiconductor Devices
Learn how to simulate carrier dynamics in semiconductor devices with 2 examples: reverse recovery and forward recovery PIN rectifier models.

Keynote Video: Simulating the Drying of Cellular Foods
How about them (dried) apples? Empa uses multiscale modeling to analyze the dehydration of soft cellular food products, such as dried fruit, and scale their processes for mass production.

How to Model Piezoelectric Devices as Both Transmitters and Receivers
Certain types of transducers can act as both transmitters and receivers. We demonstrate how to use 2 features for modeling this type of piezoelectric device.

Keynote Video: Improving Synchrotron Light Sources with Applications
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.
