 New Project Will Improve Chip Performance

University at Buffalo researchers from multiple departments will play a key role in the new $7.5 million project.

Semiconductors are vital in every area of our lives. Although in most cases, they perform as intended, often they can fail when least expected. Manufacturing them is also a very complex process with many stages that can provide lower yields than expected yields due to defects in the materials made to manufacture

Antenna Turns Radio Waves into Electricity

The researchers tested their metamaterial-based antenna in an anechoic chamber. The radio wave is sent out from the horn antenna on the left and received by the metasurface antenna mounted on the wood frame on the right. The anechoic chamber eliminates background signals from other sources and prevents stray signals from the radio wave source from bouncing around the room and perturbing measurements. The image of metamaterial-based antenna is enlarged on the right.

Radio emissions from mobile phone networks could be captured to wirelessly power sensors and other electronic components   While energy harvesting technology is still in its infancy, it is a fascinating subject.
