Engineers' new metamaterial doubles up on invisibility (w/ Video)

(Phys.org) —The new material's artificial "atoms" are designed to work with a broad range of light frequencies. With adjustments, the researchers believe it could lead to perfect microscope lenses or invisibility cloaks.

The new world of gamma-ray optics

Scientists discover that certain materials like silicon or gold exhibit a surprisingly large refractive index for extremely high energetic gamma-rays.

Carbon nanotube forest camouflages 3-D objects

Carbon nanotubes, tiny cylinders composed of one-atom-thick carbon lattices, have gained fame as one of the strongest materials known to science. Now a group of researchers from the University of Michigan is taking advantage ...
