That obstacle to progress looks to be at an end, as a group of optical engineers at Stanford has succeeded in designing a broadband metamaterial that exhibits a negative refractive index over nearly the entire rainbow...
The broad bandwidth of the new Stanford metamaterial suggests that this new class of materials will one day allow the fabrication of invisibility cloaks that are truly invisible, at least to the human eye. Beyond this, the extraordinary freedom to control light with metamaterials is likely to lead to hordes of applications never previously imagined.

Imagine the impact on eavesdropping and spying.
