What was discovered
Artificial structures of metal rings and wires refract microwaves the 'wrong' way, realising the negative-index material imagined by Veselago in 1968. Optical properties can be designed geometrically beyond what nature offers.
The result was debated until its confirmation in 2003.
What it led to
- Transformation optics and invisibility cloaks (2006)
- Superlenses beyond the diffraction limit
- Metasurfaces and flat antennas
- Metamaterial acoustics and seismology
Built on
- Veselago's theory (1968)
- Pendry's proposal of resonant rings (1999)
- Photonic crystals (Yablonovitch, 1987)
Made possible
- Metasurfaces for flat lenses
- Metamaterial antennas
- Perfect absorbers
