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...]
Interference Has Scientific Observatory Considering Move
A proposed light rail transit line installation could affect a crucial scientific observatory and jeopardize a national network used to monitor weather in space, according to documents made available to news media this week. Internal documents reviewed by The Canadian Press reportedly reveal Natural Resources Canada’s (NRCan) concerns that the installation of a $2.1-billion … [Read more...]
Researchers Achieve New Wireless Transmission World Record
Researchers in Germany have reportedly set a new world record for wireless data transmission using a combination of photonic and electronic technologies. In a successful experiment at the Karlsruhe Institute of Technology, researchers were able to transmit 100 Gbs of data per second at a frequency of 237.5 GHz over a distance of 20 meters. Previous attempts have yielded rates … [Read more...]
Technology Prevents Dropped Calls in Disaster Situations
A new solution created by a University of British Columbia graduate student could prevent dropped calls and text messages in disaster situations by using television and radio channels to transmit cellular signals when telecommunication systems are overloaded. Because wireless towers are designed to handle a specific amount of call volume, a sudden or drastic increase in the … [Read more...]
New Device Manipulates Millimeter Waves for Smaller Short-Distance Communication Systems
Researchers in Singapore have created a device capable of manipulating radio frequency signals that could lead to the development of smaller short-distance communication systems. Known as a subharmonic passive mixer, the device, built by Rui Li and her colleagues at the A*STAR Institute of Microelectronics, can convert millimeter waves from one wavelength to another. … [Read more...]
New Inflatable Antenna Could Extend Reach of Tiny Satellites
A new inflatable antenna design developed by researchers at MIT may significantly increase the communication range of small satellites, enabling them to travel further from Earth. Tiny satellites are making space exploration more accessible by enabling space agencies such as NASA to launch them into space at a fraction of the weight and cost of traditional satellites. However, … [Read more...]
