There are two papers on metamaterials worth highlighting this week:
(1) M. Burresi, et al. Probing the Magnetic Field of Light at Optical Frequencies. Science 326, 550 (2009).
The authors used concepts from the field of metamaterials to probe the magnetic field of light with an engineered near-field aperture probe. [...]
There's also a complimentary perspective article titled "Glimpsing the Weak Magnetic Field of Light" by Harald Giessen and Ralf Vogelgesang with some insights on Heinrich Hertz mind.
(2) And, another paper from Xiang Zhang's group:
Jensen Li et al. Experimental demonstration of an acoustic magnifying hyperlens. Nature (Advance publication online) DOI: 10.1038/NMAT2561.
The authors report the experimental demonstration of an acoustic hyperlens that magnifies subwavelength objects by gradually converting evanescent components into propagating waves. [...]
