U.S. Air Force Verifies Electromagnetic Pulse Weapon
The Boeing Company has developed an electromagnetic pulse weapon that can target and destroy specific electronic systems in buildings. The weapon was specifically designed to target certain buildings without causing collateral damage or injuries. Previously, this technology was only available to Hollywood screenwriters; this technology is portrayed in Warner Brother’s “Ocean’s … [Read more...]
Navy Conducts First On-board Testing of Electromagnetic Catapult
The U.S. Navy fired the first on-board catapult shots using the Electromagnetic Aircraft Launch System (EMALS) on the Gerald R. Ford CVN 78. The EMALS uses bursts of electromagnetic energy to launch planes into the air more efficiently. The EMALS offers increased reliability and efficiency, higher-launch energy capacity, more accurate speed control, and a smoother acceleration … [Read more...]
Anti-jamming Technology Effective in Protecting Satellites from Interference
Boeing Engineers have tested an anti-jamming technology for satellites that shields signals from interference and have proven the technology is capable of operating both on the ground and in a satellite-based networking hubs. The test was completed under a contract for the U.S. Air Force Space and Missile Systems Center and was supervised by the U.S. Government. It was … [Read more...]
EMC/EMI Conference Expands to U.S. Market
Horizon House Publications and Microwave Journal announced that the Electronic Design Conference and Exhibition, EDI CON, is expanding into the U.S. market after three successful events in Beijing, China. According to the Microwave Journal, EDI CON China grew 10-20 percent each year and the event had more than 2,600 attendees this year. The first ever EDI CON USA will take … [Read more...]
New Four-quadrant Voltage Drop Simulator for Automotive Testing
EM Test now offers a four-quadrant, bi-polar voltage drop simulator - the VDS 200Q Series. The amplifier can “source and sink current using a programmed voltage in both positive and negative polarities. The amplifier generates dips and drops, short interruptions and voltage variations to simulate a wide range of phenomena occurring on a vehicle wiring harness,” according to … [Read more...]
Log Video Amplifiers Perform Up to 18 GHz
Pasternack announces a new line of broadband logarithmic (log) video amplifiers that cover bandwidths from 0.5 GHz to 18 GHz. The amplifiers utilize GaAs semiconductor technology, which makes them ideal for use in measuring signals at high frequencies in high speed applications. “These log amplifiers can process up to 75 dB of dynamic range and have log linearity that ranges … [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...]
