First Acoustic ‘Superlens’

Facebook X LinkedIn Email
CHAMPAIGN, Ill., June 25, 2009 – The world’s first acoustic “superlens,” an innovation that could have practical implications for high-resolution ultrasound imaging, nondestructive structural testing of buildings and bridges, and novel underwater stealth technology, has been created by researchers at the University of Illinois. The team, led by Nicholas X. Fang, professor of mechanical science and engineering, successfully focused ultrasound waves through a flat metamaterial lens on a spot roughly half the width of a wavelength at 60.5 kHz using a network of fluid-filled Helmholtz resonators. According to the...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
