New Methods Minimize Interference on TV Broadcasting and Mobile Connections
A research project recently conducted by VTT Technical Research Centre of Finland Ltd. allows an optimal location to be identified for wind turbines, where interference on television broadcasting and mobile connections is minimized. “With tools now available for minimizing the potential negative impacts of wind power at the planning stage, power plant projects are likely to … [Read more...]
‘Electrosmog’ to Help Power Devices in UK
Paul Drayson, a former British science minister, has developed a device that captures “electrosmog” (invisible clouds of electromagnetic radiation), and uses it to power small devices. The energy-harvesting system is known as Freevolt. Freevolt uses an antenna to gain power from multiple wavebands of the electromagnetic spectrum. This is the first commercial device that is … [Read more...]
New Multi-Range System DC Power Supply Model
B&K Precision has introduced an addition to its 9115 Series with the new multi-range programmable DC power supply—model 9117. The new 9117 can deliver up to 3000 W of output power in any combination of voltage up to 80 V and current up to 120 A within its power rating. It offers twice as much output power as current models in the 9115 series and has a 2U 19" rackmountable … [Read more...]
GaN Coaxial Power Amplifiers
Pasternack recently launched its increased offering of gallium nirtride (GaN) coaxial power amplifiers. “The high power density of gallium nitride semiconductor technology dissipates heat more effectively which results in amplifier designs that have significantly higher output power levels over broadband and narrowband frequencies,” according to the company. This technology … [Read more...]
New Metamaterial Yields Invisibility for Aircraft and Drones
Electrical engineers from the University of California have created a new ultra-thin metamaterial that could provide a cloaking device and make UAVs (Unmanned Aerial Vehicles) invisible. The new material creates invisibility and leaves no electronic, infrared or visual signatures for enemies to detect. The new design uses “an ultra-thin Teflon substrate, studded with … [Read more...]
