BEAST Technology Allows Scientists to Study Metal-Surface Hotspots

Researchers at the Lawrence Berkeley National Laboratory have created a BEAST - a device that probes into the electromagnetic field created when light strikes metal, entering an area of research previously off-limits to scientists that could increase the efficiency of solar-powered energy devices. Research of the technique, also known as the Brownian Emitter Adsorption Super-resolution Technique, was published in the Jan. 20 issue of the journal Nature. The method has enabled scientists for the first time to measure the electromagnetic field inside a hotspot - an area of metal often only a few nanometers in size where the light's rays cause electrons to oscillate, creating an electromagnetic field.
