Optics with electrons
LENS anniversary, Albert Polman from Holland: how to engineer materials to obtain negative refraction indexes and a moonwalking light.
From the invention of sparking magnet by Leopoldo Nobili in the late eighteenth century, now physicists can produce metamaterials with strange properties such as negative diffraction index, fundamentally based on that idea. Key-concepts are engineering of subwavelength structure of materials and design of small resonators.
For example, modern techniques allow to work also with visible light and to produce perfect lenses, manipulate optical space, obtain strange effects such as moonwalk for light.[video=640 512]Ventesimo_pomeriggio_Albert_Polman[/video]
