[Noisebridge-discuss] metatronics - using light instead electricity

The "meta" in "metatronics" refers to metamaterials, the 
relatively new field of research where nanoscale patterns and structures 
embedded in materials allow them to manipulate waves in ways that were 
previously impossible. Here, the cross-sections of the nanorods and the 
gaps between them form a pattern that replicates the function of 
resistors, inductors and capacitors, three of the most basic circuit 
elements, but in optical wavelengths.
"If we have the optical version of those lumped elements in our 
repertoire, we can actually make designs similar to what we do in 
electronics but now for operation with light," Engheta said. "We can build 
a circuit with light."
