Hi All,
The "twist" in the radio waves is "Orbital Angular Momentum".
If you're interested in a more technical explanation of this phenomenon, take a look at the following document to be published in the IEEE Transactions on Antennas and Propagation:
http://www.lunduniversity.lu.se/o.o.i.s?id=24732&postid=2062936
The paper is a little hard to follow with all it's equations. The conclusion is that using Orbital Angular Momentum provides no more bandwidth than using MIMO (Multiple in multiple out) techniques.
