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...]
Serbian President Dedicates Nikola Tesla Monument at Wardenclyffe Laboratory
A life-sized granite statue of Nikola Tesla was unveiled Monday by Serbian president Tomislav Nikolic in a dedication ceremony honoring the late Serbian-American scientist. The monument stands near Wardenclyffe laboratory in Shoreham, N.Y. where Tesla did most of his work on wireless transmission between 1903 and 1915. The 16-acre property was purchased earlier this year by … [Read more...]
Researchers Control Electromagnetic Waves with Help from 3-D Printer
A team of scientists from the University of Texas at El Paso have developed a way to control electromagnetic waves in three-dimensional space using plastic metamaterials created with a 3-D printer. “When you fold electromagnetics into three dimensions, the components interfere with one another, and it becomes a confusing electromagnetic mess where nothing will work—like when a … [Read more...]
Microwave Oven Powers Small Devices with Electromagnetic Energy
Scientists in Japan have discovered a way to run kitchen appliances using electromagnetic energy scavenged from microwave ovens. While the majority of radiation generated by the common kitchen appliance is directed at the food inside the device, a portion of the energy can still escape through the gap around the door and through the metal-meshed window. So, for consumer … [Read more...]
New EMC Facility May Lead Next-Gen Wireless Development
A new $15 million facility at the University of Waterloo, Canada is expected to contribute significantly to the development of next-generation wireless technology. Featuring four interconnected indoor laboratories, one outdoor lab and an advanced computational facility, the new 5,000 sq. ft. Centre for Intelligent Antenna and Radio Systems (CIARS) is said to offer the highest … [Read more...]
EMC Pioneer Ralph Showers Passes Away
Ralph M. Showers, Ph.D., of Havertown, Penn passed away at his home on Sunday, September 8, 2013. The IEEE EMC Society founder was 95. Born in Plainfield, N.J., he received his undergraduate and doctoral degrees from the University of Pennsylvania before becoming a professor at the Moore School of Electrical Engineering at the University of Pennsylvania. He was named emeritus … [Read more...]
Antenna Network Wirelessly Powers Devices
A new system provides wireless power to electronic and electrical devices using a series of antennas embedded underneath a surface, removing the need for electric cables. The Smart University Power Antenna (SUPA) Wireless technology uses a principle similar to that of induction cookers, according to researchers from the Fraunhofer Institute for Electronic Nano Systems (ENAS) … [Read more...]
Communication System Powers, Connects Battery-Less Devices
Engineers at the University of Washington have created a new communication system that takes advantage of wireless signals to power electronic devices without relying on batteries or wires. Known as ambient backscatter, the technique enables battery-less devices to exchange information with each other by repurposing existing Wi-Fi, mobile and television signals to act as both … [Read more...]
Astronauts Test Electromagnetic Propulsion Technology Aboard ISS
A new electromagnetic propulsion technology being tested on the International Space Station has the potential to extend the lifecycle of satellites and future spacecraft by providing a renewable power source. Created by researchers from the University of Maryland’s Space Power and Propulsion Laboratory (SPPL), the Resonant Inductive Near-field Generation System (RINGS) uses a … [Read more...]
