(Phys.org) —Radar systems today depend increasingly on phased-array antennas, an advanced design in which extensive grids of solid state components direct signal beams electronically. Phased array ...

Researchers at the Georgia Institute of Technology have devised a passive time-delay component which will make phase-array radars smaller, simpler, more efficient, and less expensive. The thin-film ...

Tsukuba, Japan—Airborne ultrasonic phased arrays focus ultrasonic waves at prescribed locations in space and dynamically steer them, enabling applications such as noncontact tactile feedback, odor ...

A research team from Georgia Tech has developed an ultra compact passive true time delay; a move that could help to reduce the size, complexity, power requirements and cost of phased array radar ...

Holodeck, anyone? Researchers at Bristol University are developing a system known as UltraHaptics that uses ultrasonic force fields to project the tactile sensations of objects in midair. Currently ...

GuRu Wireless has announced a mm-wave phased array with over 70,000 transmitters, intended to transmit power wirelessly to persistent drones. “Our current transmitter can deliver over a kilowatt of ...

Researchers have developed an ultra-compact passive true time delay device that could help reduce the size, complexity, power requirements and cost of phased array designs. The device uses the ...
