Troubleshooting Radiated Emissions Using Low-Cost Bench-Top Methods

 

Kenneth Wyatt Wyatt Technical Services LLC Editor's Note: Click on the pdf icon at left for a printable copy of this article. Because time-to-market and budget factors often drive many of today’s high-tech designs, electromagnetic compatibility (EMC) issues often surface at the last moment in the design cycle, potentially delaying product introductions. Very often, simple … [Read more...]

Light Painting Wi-Fi

 

In the video “Immaterials: Light Painting Wi-Fi,” a team of Norwegian researchers combined long-exposure photography with Wi-Fi signal detection to plot what happens to wireless signals when they intersect with common objects. To achieve the layering of electromagnetic terrain on top of everyday scenery, the three filmmakers constructed a 4-meter-tall Wi-Fi measuring rod. A … [Read more...]
