IT is very easy to form a mental picture of the displacements in an isotropic elastic solid transmitting a plane transverse wave. Alternate planes of constant phase are sheared relatively to one ...

WASHINGTON — Researchers have designed and demonstrated two all-silicon terahertz metasurface devices that can be used to create four optical channels for simultaneously implementing different optical ...

A pair of space zombies show that dead stars are still capable of incredible physics. Researchers found this out when they studied data from one of the most important astronomical events of the last ...

It is shown that certain anisotropic elastic materials can have one or two sheets of spherical slowness surface. The waves associated with a spherical slowness sheet can be longitudinal, transverse or ...

Reservoir computing (RC) stacks a few benefits over other artificial neural networks, such as the reservoir that gives this technique its name. The reservoir functions mainly to nonlinearly transform ...
