There are curious contradictions found:
"This novel radio technique allows the implementation of, at least in
principle, an infinite number of channels on one and the same
frequency, even without using polarization or dense coding
techniques."
compared with:
"Already with this setup one can obtain four physically distinct
channels on the same frequency by additionally introducing the use of
polarization, in this case independent from OAM. A further
multiplication of a factor five after the implementation of
multiplexing, yields a total of 20 channels in the same frequency."

Soooo. A special vorticity technique that does not use polarization
(even though they describe it as such) and does not use coding, can
demonstrate novel outcomes when paired with polarization and coding
(for which the outcome is fairly well established).

Why isn't this peer reviewed in EM proceedings?

If I were to hazard a guess, this sounds like another holy grail dream
for the digital folks. Many who just inherently "know" that bandwidth is
infinite and can support infinite data.

Imagine - the entire universe playing Angry Birds at the same time. The
mind boggles!
