Radio waves twisted into the shape of fusilli pasta have been beamed
across Venice – and researchers discovered that they allow for a
potentially infinite number of channels to be broadcast and received.
The researchers, from the University of
Padova, Italy, and the Angstrom Laboratory, Sweden, believe that they
have solved the problem of radio congestion.
As the world continues to adapt in the
digital age, the introduction of new mobile smartphones, wireless
internet and digital TVs means the number of radio frequency bands
available to broadcast information gets smaller and smaller.
‘You just have to try sending a text message at midnight on
New Year's Eve to realise how congested the bands are,’ said lead
author Dr Fabrizio Tamburini.
