matter and light

New insights into how light interacts with matter have been found by researchers in the US. Rick Lytel, Mark Kuzyk, and colleagues, at Washington State University, Pullman, have developed a heuristic approach that first involves throwing a metaphorical dart at the materials target and hoping, if not for a bullseye, then a high score in terms of photon interaction with the structure of the material. Once they have a hint of a powerful response, they can use computational methods to nudge their dart closer to the bullseye until they find a structure that will respond in the desired way.
