A new study shows that metamaterials can be designed to do "photonic calculus" as a light wave goes through them. A light wave, when described in terms of space and time, has a profile that can be ...

Analog computers have been used extensively in the past, for things like tide calculations, but in the semiconductor era things have mostly gone digital. Even where you have analog elements, like DRAM ...

(Nanowerk News) The field of metamaterials has produced structures with unprecedented abilities, including flat lenses, invisibility cloaks and even optical "metatronic" devices that can manipulate ...

An analog computer is a system that provides information in continuous form. These computers can only represent physical quantities such as pressure, weight, voltage pressure, speed, and more.

My first job out of college was testing and debugging control loading systems on flight simulators for 747 and the “new” 767 airliners. In the late 1970s, the control loop that simulated the feel of ...

Researchers at Cornell University have developed an electronic chip that they describe as a "microwave brain." The simplified chip is analog rather than digital, yet can process ultrafast data and ...

Update: We are resurfacing this feature from 2014 for your reading pleasure on this holiday weekend. The USS Zumwalt, the latest destroyer now undergoing acceptance trials, comes with a new type of ...
