[boinc news] Lenses can bend light and sound in almost any directionBOINC Pentathlon

[Boinc-feed]

(PhysOrg.com) -- When an optical fiber is bent by 90° or more, the light begins to leak away, posing a problem for fiber optics communications. But by using special lenses that can bend light by not only 90°, but also 180° (i.e., a U-turn) or 360° (i.e., a full loop), scientists may limit light leakage in optical fibers and overcome this problem, not to mention provide a useful material for many other applications. Recently, a team of scientists has theoretically investigated materials for achieving this kind of advanced light control, which could work equally well for sound waves.Team SETI.Germany continues its new challenge and invites all BOINC Teams to participate in the 3rd BOINC PENTATHLON, following the ideals of the ancient Greek Pentathlon. .
