Boyd Team's Theory Predicts a Way Around Bandwidth Limit

A new publication in Science by a team including The Institute's Prof. Robert Boyd uses electromagnetic theory to predict a means to surpass a bandwidth limit for "high-Q systems."  The "quality," or "Q," of a system represents how easily the system can absorb energy at its natural resonant frequency.  According to the article, higher-Q systems have narrower bandwidth--a narrower range of frequency over which they can absorb energy--but this range may be broader in "asymmetric systems."  The abstract (and full text for AAAS members) is here.
