So-called Rayleigh–Bloch waves can release an enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency ...

The terms on the left-hand side of Equation 2 represent wave action density change in time, propagation in geographical space, shifting of the relative frequency due to changes in current and depth, ...

Ministry of Information and Broadcasting today marked a significant milestone in the lead-up to the World Audio Visual & Entertainment Summit (WAVES) with the launch of major initiatives at the ...

(NASA via AP) NEW YORK (AP) — Scientists have detected cosmic waves that sound like birds chirping in an unexpected place. These bursts of plasma, called chorus waves, ripple at the same frequency as ...

Bikers are in a club of their own even if they don't know each other and that club includes private waves. It's called the biker wave and it's pretty simple with four total. The wave with two ...

Reflection in action is the ability to think about what you are doing while you are doing it, and to adjust your actions accordingly. It is a form of tacit knowledge, or knowing-in-action, that ...

Here a broadband dual-polarized Huygens’ metasurface is proposed to realize high efficient terahertz wave anomalous refraction. By constructing simultaneous electric and magnetic responses in a ...
