Circular polarizer at the nanoscale. Recently, metamaterials, by means of which electromagnetic waves, including light, can be manipulated, have fired the researchers’ imagination. These artificial structures possess properties that cannot be found in nature. Perfect lenses without aberrations and even invisibility cloaks à la Harry Potter can be made of metamaterials, at least theoretically. Now, scientists from the Karlsruhe Institute of Technology (KIT) describe, for the first time, three-dimensional metamaterials that could really be applied in spectroscopic measurement instruments. The work, now reported by the renowned journal Science as a highlight on its website prior to the publication of the printed version, ... [more]
