Electromagnetic Cloaking System Cancels Out Radio Waves
A new approach to invisibility cloaking from researchers at the University of Toronto, Canada has yielded an adaptable system capable of shielding objects of various sizes from radar detection. Developed by professor George Eleftheriades and Ph.D. student Michael Selvanayagam of The Edward S. Rogers Sr. Department of Electrical & Computer Engineering, the cloaking system … [Read more...]
Toyota Calls for More Testing to Prevent Connected Vehicle Interference
Toyota Motor Corp. is concerned that expanding Wi-Fi services could interfere with future auto safety technology and believes more testing is needed to ensure no such problems arise. Principal research manager John Kenney of the Toyota Info Technology Center in California told a U.S. House Energy and Commerce panel overseeing technology that the Federal Communications … [Read more...]
Robot Arm Aids in High Frequency Antenna Calibration Breakthrough
A new antenna testing method from researchers at the Physical Measurement Laboratory (PML) in Colorado could lead to greater accuracy in the characterization and calibration of antennas for use at 50 GHz to 500 GHz. Currently, “there are no international reference standards for antennas at these frequencies,” team member David Novotny of the Radio-Frequency Fields Group in … [Read more...]
RF Tuning Technology Could Increase Available Frequency Range in Wireless Devices
Scientists have announced a new research breakthrough they say could increase the range of wireless frequencies available in smartphones and other wireless devices while simultaneously reducing manufacturing costs. Researchers at Northeastern University, in cooperation with Semiconductor Research Corporation (SRC), found that the application of a certain amount of voltage to a … [Read more...]
Metamaterial Power Harvester Boasts Solar Cell Efficiency
Researchers at Duke University’s Pratt School of Engineering in North Carolina have created a power-harvesting device that can be tuned to capture energy from various sources, including satellite, sound and Wi-Fi signals, and convert it to direct current voltage capable of charging small electronic devices. While the new device is not the first “energy-harvester” ever created, … [Read more...]
New Type of Filter May Help Bring Order to Crowded Radio Spectrum
Scientists from the Netherlands have developed a new type of filter based on micromechanical resonators they say is ideal for maintaining order amidst the expected future growth of frequency standards. According to researchers at the MESA+ Institute for Nanotechnology at the University of Twente, the new solution consists of two mechanical resonators that vibrate at an … [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...]
