Cracks in the System – Thermomechanical Fatigue of Electronics Components, Part 2

As discussed in Part 1, engineers are tasked with designing electrical components that can withstand the increased thermal and mechanical loads required of today’s ever-more-powerful electronics. Sometimes these are entirely new designs built from the ground up, and subjected to holistic testing and prototyping during the R&D phase. But often, manufacturers seek to merely tweak […]

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

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

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
