Community News - Analogue Computing with Metamaterials?

Posted on February 03, 2014

Most modern computing relies on digital technology, but this was not always the case. Early computing used analogue techniques, operating on continuous voltages and currents, to perform calculations.

Now, a report in Science describes a theoretical metamaterial that performs calculus on light waves that propagates through it. Apparently, the cross-sectional profile of the incident light is transformed into a new profile equal to the derivative of the original profile. This could have applications in image processing and even potentially enable further speed increases in particular applications of computing.
