Stories from Physics for 11-14 14-16 IOP RESOURCES

A team of Italian and Swedish researchers have found a way to develop fusillishaped radio beams, with a view to reducing radio wave congestion. The popularity of mobile phones means that the number of radio frequency bands available is decreasing. By twisting radio waves clockwise or anti-clockwise about their axis, the researchers found that multiple signals could be transmitted on the same frequency channel without interference.
