Scientists Warn Earth Would Have 15 Minutes to Prepare for Solar Flare; Need to Develop Adequate Protection Now

 

As the sun continues to enter the peak of its 11-year cycle of magnetic activity, scientists around the world are becoming increasingly concerned about the possibility that a solar flare—a plasma cloud of charged particles—emitted by a solar superstorm could destroy global electronics networks with as little as a 15-minute warning. “Our message is, don’t panic, but do prepare … [Read more...]

New “DC Invisibility Cloak” Could Be Used to Disguise Military Vehicles

 

Researchers in China have developed a “DC invisibility cloak” to hide electrical and magnetic signals that are generated by direct current. The new invisibility cloak has the potential to disguise infrared and magnetic signatures given off by military weapons, aircraft and ground vehicles. Comprised of a network of resistors that assist in “bending” the electromagnetic waves, … [Read more...]

EMC Engineers Come Bearing Gifts

 

It’s the holiday season again, when we celebrate the serious things in life and have some fun too.When EMC engineers come bearing gifts...tis NOT the season to be jolly.  Fa-la-la, le-la-la-laa.  In fact, it’s time to be worried. For to the EMC engineer, GIFTS is an acronym for: Grounding, Isolation, Filtering, Transient suppression, and Shielding. Sometimes it takes … [Read more...]

Potential Impacts of Electromagnetic Weapons on the Critical Infrastructures (View from 2012)

 

William A. Radasky IEEE Life Fellow WHAT IS IEMI? In recent years, Hollywood has indicated that criminals and terrorists could use electromagnetic (EM) weapons to black out a portion of Las Vegas (Ocean’s 11) or take down a counter-terrorism computer center (24).  Is this fact or fiction?  It turns out that Hollywood in this case is leading the public and police agencies in … [Read more...]
