An acoustic amplifier developed by Sandia National Laboratories researchers measures 0.5 mm2 (0.0008 square inches), and is more than 10 times more effective than the earlier versions. The acousto-electric chip includes a radio-frequency amplifier, circulator and filter; SEM image shows details of the amplifier. Image credit: Bret Latter / Matt …

Here’s a new invention that, while potentially useful, is even more interesting as an illustration of the nature of sound: the acoustic prism. When light enters a prism made of some refractive material, the sub-components of that light have their paths affected slightly differently, based on their wavelength (color); the …
