Technology Review: Blogs: arXiv blog: New Type of ‘Metalens’ Shatters Diffraction Limit
Ten years ago, classical optics was but a sleepy backwater of modern physics, a place to while away the hours in the autumn of your career.
Then all hell broke loose with the development of metamaterials, perfect lenses and invisibility cloaks, prospects that now make optics one of the hottest areas in science.
Nor the comet that came unannounced out of the north, flaring in heaven;
Nor the strange huge meteor procession, dazzling and clear, shooting over our heads,
(A moment, a moment long, it sail’d its balls of unearthly light over our heads,
Then departed, dropt in the night, and was gone;)
