This network can directly process and recognise diffractive information with low power consumption and at the speed of light, broadening the application of terahertz plasmonic metamaterials.

It now seems that manmade chiral metamaterials may provide an answer ... can be fabricated to provide a negative index in the terahertz and microwave regions. Both results make use of chirality ...

To fulfil their potential, metamaterials need a magnetic component ... This is certainly true in the case of sources of light at terahertz frequencies, which were once practically unavailable.
