Efficient time-reversed light pulses developed
LONDON – Physicists have taken advantage of the properties of periodic systems to efficiently time-reverse ultrashort electromagnetic pulses for applications in medical ultrasound, optical communications, superlensing, ultrafast plasmonics and biological imaging. Because a time-reversed pulse evolves as if time were running backward, time reversal eliminates any distortions or scattering that has occurred at earlier times, regardless of the medium the pulse has propagated through. Research of this time...
Gold nanoantenna enhances plasmonic sensing
BERKELEY, Calif. – The first reported experimental demonstration of antenna-enhanced gas sensing at the single-particle level holds great promise for plasmonic sensing. By placing a palladium nanoparticle on the focusing tip of a gold nanoantenna, researchers with...
