Hyperlens crystal can image 360 times smaller than infrared wavelength down to 30 nanometers
hexagonal boron nitride (hBN) is a natural crystal with hyperlensing properties. The best previously reported resolution using hBN was an object about 36 times smaller than the infrared wavelength used: about the size of the smallest bacteria. The new paper describes improvements in the quality of the crystal that enhance its potential imaging capability by …
