University of Twente researchers have developed a breakthrough technique that dramatically enhances radio signal generation on computer chips. The method uses surface acoustic waves, dubbed "mini earthquakes," created by a thin glass layer to strengthen interactions between light and sound by more than 200 times.
The advancement addresses a longstanding challenge in electronics engineering where light-sound interactions on chips were too weak for practical applications. Modern technology from GPS satellites to mobile networks depends on ultra-precise radio signals, making this development significant for the telecommunications industry.
