A.H. Systems recently sponsored an EMC Live webinar on selecting antennas for today’s test requirements in which I introduced a simplified method of establishing the amplifier power required by an above 1GHz RF immunity system. Existing methods, such as slotting numbers into a spreadsheet, do not provide the necessary visualization of the test system behavior, and provide … [Read more...]

Maglev Hovering Train Breaks Speed Record
A seven car Maglev (magnetic levitation) Train in Central Japan broke its own speed record when tested near Mount Fuji this week. In 2003 the Maglev’s record was 268 mph and last week it reached 366 mph. On Tuesday the Maglev surpassed both previous records and reached 374 mph. The Maglev train hovers four inches above the tracks and is propelled by electrically-charged … [Read more...]
Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking
Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]
FBI Pulled Security Expert from Flight for Alleged Hacking Concerns
The FBI pulled Chris Roberts, a computer security expert, from his United Airlines Flight last Wednesday in Syracuse because of suspicions that he hacked the airplane. Roberts tweeted referencing the plane’s communication systems suggesting he was going to use his laptop to force the plane’s emergency oxygen masks to deploy. The tweet read: “Find Myself on a 737/800, let’s see … [Read more...]
