From the headphones we use to listen to our favorite songs or podcasts, to sonic camouflage employed by submarines, how we transmit and experience sound is an essential part of how we engage with our surrounding world. Acoustic ...
Playing back recorded audio from digital storage allows us to enjoy music without the physical presence of a musical instrument to generate resonating sound. In a seemingly unrelated area called metamaterials, scientists ...
A research team of Vanderbilt engineers that includes a scientist at Oak Ridge National Laboratory has demonstrated a new ultrathin filter, based on metamaterials, that allows for analog optical image processing. Their work, ...
By making specially designed slits in Plexiglas, Danish researchers have made it stronger, lighter and more flexible. The new knowledge could be used to make microchips, for example, much more durable.
Reciprocity isn't always a good thing.
Electrons race along the surface of certain unusual crystalline materials, except that sometimes they don't. Two new studies from Princeton researchers and their collaborators explain the source of the surprising behavior ...
3-D printers working in the millimeter range and larger are increasingly used in industrial production processes. Many applications, however, require precise printing on the micrometer scale at a far higher speed. Researchers ...
When you knock on a melon to see if it's ripe, you are using sound waves to probe the structure of the material inside. Â鶹ÒùÔºicists at the University of Chicago were using the same concept to explore how sound waves travel ...
Metamaterials have properties that depend on their shape and architecture. Researchers at AMOLF, Leiden University and Tel Aviv University have found a new way of designing these metamaterials and their properties by deliberately ...
Analog machine learning hardware offers a promising alternative to digital counterparts as a more energy efficient and faster platform. Wave physics based on acoustics and optics is a natural candidate to build analog processors ...
