Radio Frequency Device Stops Vehicles in Their Tracks
British engineers have developed a new prototype device that uses electromagnetic pulses to stop moving cars and other vehicles E2V’s RF Safe-Stop uses radio frequency pulses to disrupt a vehicle’s electronic systems, causing the engine to shut down. The device could be used by the military to prevent unauthorized vehicles from entering restricted areas, or by the police to … [Read more...]
New Tool Detects and Traces Electromagnetic Attacks
With the ability to interfere with or damage electronic devices, electromagnetic pulses (EMP) are considered one of the most dangerous threats facing modern electronic systems and infrastructure. Man-made EMPs in particular can be used to deliberately disable power grids and defense and security systems without leaving any indication as to the specific nature or origin of the … [Read more...]

Researchers at the University of Buffalo, N.Y. have developed an underwater wireless network that could one day improve tsunami detection, offshore oil and natural gas exploration, military and law enforcement applications, pollution monitoring and other similar activities. The new system will solve one of the main problems facing underwater data transmission, says Tommaso … [Read more...]
Dolphins Inspire Radar System to Detect Hidden Electronics
Dolphins have inspired British researchers to create a new type of radar device that can detect hidden surveillance equipment and explosives and help locate buried avalanche or earthquake victims. According to New Scientist, the idea came to Timothy Leighton of the University of Southhampton’s Institute of Sound and Vibration Research while he was watching a nature show. After … [Read more...]
Military Tests Aircraft Injection-Jamming Simulation Software
The SPACE JAM system utilizes an algorithm that injects realistic GPS jamming effects directly into an aircraft's navigation system. (Image: Rebecca Amber / U.S. Air Force)A new jamming simulation project being tested by U.S. Air Force students may lead to better training methods and emergency protocols to combat Global Positioning System (GPS) disruption. Originally designed … [Read more...]
New Band-Pass Filters with Center Frequencies from 1.4MHz to 200MHz
IQD Frequency Products has introduced the new IQXF-1000 series, a range of band-pass filters with center frequencies from 1.4MHz to 200MHz based around fundamental and third overtone mode crystals.
