The demonstration of a Yagi–Uda nano-antenna that operates at visible wavelengths gives hope for a convenient means of directing radiation patterns from nanoscale light sources such as single ...

Directing the fluorescence from nanoscale emitters such as single molecules and single quantum dots is a key factor in a wide range of applications, from the efficient detection of molecules for ...

One of the first things that an amateur radio operator is likely to do once receiving their license is grab a dual-band handheld and try to make contacts with a local repeater. After the initial ...
