Physicists in the US have created the first nanoscale coaxial cables for the transmission of light. Operating much like the coaxial cables used to distribute television and radio signals, the cables ...

A transmission line is a far more complex piece of equipment than many people realize. In its simplest form it may be considered as just a pair of wires merely carrying ac power. Usually in these ...

Coaxial cables transmit radiation with a wavelength much bigger than their diameter. Now, a miniature version borrows this concept to carry visible light at the nanoscale. Researchers in nanophotonics ...
