Jason Cole, a programmer and Ph.D. student at Imperial College in London, created an Android app that allows users to hack their own Wi-Fi using electromagnetic waves. Many believe it’s best to avoid electromagnetic radiation; however, not all believe electromagnetic waves are bad. Electromagnetic waves carry Wi-Fi signals to all electronic devices and are the foundation of … [Read more...]
FCC to Vote on Airwaves Sharing Plan
The Federal Communications Commission (FCC) will vote next month on a plan that will allow companies and wireless carriers to share airwaves with the government. The FCC has been working to increase the spectrum for many years and has set aside frequencies for new Wi-Fi networks. This sharing plan was designed to make more airwaves available for future wireless devices. “The … [Read more...]
Naval Exercise Causes Mobile Phone Black Spot
Plymouth Sound, a bay in England, lost mobile phone signal during a naval exercise last week. The navy said it was testing new ‘communication equipment’ when a mobile phone black spot occurred in the PL1 and PL2 postcodes. Local residents made numerous complains to mobile network operators and as a result, Ofcom, the communications regulator in the United Kingdom, is … [Read more...]
Multilayer Ceramic Capacitor Increases Capacitance by 50 Percent
The first commercially available X5R/X6S 330μF multilayer ceramic capacitor has been produced by TAIYO YUDEN. Compared to the previous products, in the same size capacitor, capacitance increases by more than 50 percent. This capacitor was designed to replace electrolytic capacitors and to reduce noise and smooth ripple current in power supply circuits. It offers longer product … [Read more...]

A Show Report on the 2015 Santa Clara Symposium on EMC & SI
Whenever I missed an EMC show I always wished there was some sort of report I could read to get a feel for some of what I missed. To that end, here is one on Santa Clara. I have tried to make it informative and fun for non-attendees and attendees alike.This is a major event with a lot of presentations happening in parallel, and I could only attend a short time, so I apologize … [Read more...]
Physicists Discover Graphene Absorbs up to 50 Percent of Microwave Radiation
A team of physicists from the University of Namur in Belgium have discovered that graphene serves as an effective shield against microwave inference. Graphene has the ability to reduce microwave pollution and to enhance the electromagnetic compatibility of future electronic devices. Philippe Lambin, project lead, and and his colleagues demonstrated that “the conductivity of … [Read more...]
U.S. Navy Tests Electromagnetic Catapult
Traditional steam-powered catapults assist aircraft carriers’ jets and bombers in getting off the ground as quick as possible on a short runway. The U.S. Navy is now testing an electromagnetic version of a catapult on the 337-metre long USS Gerald R. Ford aircraft carrier. “The Electromagnetic Aircraft Launch System (EMALS) uses a burst of electromagnetic energy to launch … [Read more...]
