Putting on the pressure improves glass for fiber optics — ScienceDaily

Rapid, accurate communication worldwide is possible via fiber optic cables, but as good as they are, they are not perfect. Now, researchers from Penn State and AGC Inc. in Japan suggest that the silica glass used for these cables would have less signal loss if it were manufactured under high pressure. “Signal loss means that […]

Perfect transmission through barrier using sound

The perfect transmission of sound through a barrier is difficult to achieve, if not impossible based on our existing knowledge. This is also true with other energy forms such as light and heat. A research team led by Professor Xiang Zhang, President of the University of Hong Kong (HKU) when he was a professor at […]
