Researchers at MIT and the University of Birmingham have independently
published two different papers, one in Physical Review Letters and the other in
Nature Communications, where they have shown relatively large objects can be
rendered invisible to the naked eye using the material calcite.

But, he says, scaling up to 3-D isn’t too big of a leap from 2-D. Zhang imagines similar technology one day concealing submarines on the sea floor.
