(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. Researchers at ...

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 ...

Directing acoustic waves along curved paths is critical for applications such as ultrasound imaging, surgery and acoustic cloaking. Metamaterials can direct waves by spatially varying the material ...
