A new wireless power transmission system has been put up by Nihon Dengyo Kosaku and Volvo Technology Japan. Unlike previous versions developed by Dengyo, this one is able to transmit 10 kilowatts of electricity through microwaves at a distance of 4 to 6 meters. Although it is two times more powerful than what they’d already […]

NC State University researchers have recently implemented what is being used in radios for decades in wireless power transfer (WPT) receivers – the ability of the receiver to keep track of the transmitter’s frequency if the differences are really small. This could ultimately impact electric vehicle wireless power transfer systems by making them more efficient […]

Two researchers from the State Key Laboratory of Millimeter Waves at Southeast University from Nanjing, China, have discovered and prototyped a device that acts like a black hole for electromagnetic waves in the microwave spectrum. It consists of 60 concentric rings of metamaterials, a class or ordered composites that can distort light and other waves.
