Cracks in the System – Thermomechanical Fatigue of Electronics Components, Part 1

Thermomechanical Failure /

The airbags in your car; the camera on your video doorbell; the phone or other electronic device you’re reading this on right now. The everyday products that make modern life possible wouldn’t be able to run without key electrical components that maintain functionality and stability for years at a time. And yet, these electrical components […]

Electromagnetic Wave Polarization in 2D Geometry

COMSOL Multiphysics, Tips & Tricks /

An electromagnetic wave consists of a coupled oscillating electric field and magnetic field which are always perpendicular to each other. By convention, the “polarization” of electromagnetic waves refers to the direction of the electric field. In 3D geometry, arbitrary polarization is naturally defined by the prescribing the directions of all three components of the electric
