EMC in Space …
Successfully dealing with EMC in space systems requires strong EMC engineering Daryl Gerke, PE, and William Kimmel, PE Many of us in the EMC business came of age during the “space race” of the 1950s, 60s, and 70s. We well remember names like Sputnik, Mercury, Gemini, and of course, Apollo. Some of us in the EMC business have even been fortunate enough to spend some (or all) or … [Read more...]
Portable ‘Pain Ray’ Guns No Longer Science Fiction
Raytheon now markets a more portable version of its non-lethal “pain ray” weapons. The “Silent Guardian,” a part of Raytheon’s Active Denial System, uses high-frequency radio beams that make human targets feel like they are on fire. The futuristic weapon produces high-frequency millimeter waves directed toward the target by an antenna that looks like a radar dish. It directs a … [Read more...]
