What a shame!

This web site is run and published by a group of students and young graduates from departments of physics of several italian universities.
We were appalled at the statements made by Fabrizio Tamburini and his Team and very upset and disgusted by the way in which his unsubstantiated claims have been passed-off as "scientifically proven discoveries" on many specialized journals and magazines.
We have come together and decided that, for the public interest, it was time to set the records straight.
Our identities must remain secret to prevent our careers from being jeopardized.

Following the success of our initiative, we have decided to open up a discussion board on this same web site.

Naïve theoreticians got their own knickers twisted over radio waves blunder.

An italo-swedish Team hit the headlines when it announced the discovery of the photon orbital angular momentum and its vorticity in the radio frequency spectrum, in a similar way to what it happens with coherent light beams.

Later, Martin Bojowald, at Pennsylvania State University, suggested the possibility that the OAM prediction could allow the direct detection of spinning black holes.

Their "experiment" presented in a scenographic fashion in the venetian lagoon and heralded as having an importance of epic proportion turned out to be a fiasco!

NATURE, the international weekly magazine of science, is set to lose its credibility after publishing this:
http://www.nature.com/news/2011/110222/full/news.2011.114.html

PhysicsWorld.com too got it-self entangled with it by publishing this:
http://physicsworld.com/cws/article/news/2012/mar/07/physicists-put-a-new-twist-on-radio

The IEEE couldn't wait to join the club:

And the BBC has soon followed suit:

And so did Phys.org:

To the benefit of all, we have transcripted and translated into english what Fabrizio Tamburini has said on this brief but pregnant videorecording.

N.B.   We have numbered each of his sentences and have placed question marks next to them to indicate all the things that he has stated and taken for granted, although, they have no place in recognised physics.
We suppose Fabrizio Tamburini and his team hold the answers to our questions and so we will be happy to hearing from them.

1)   ... electromagnetic vortices or optical vortices are nothing else than other properties, other degrees of freedom (??? Q1) of the electromagnetic field.
2)   In the same way light has the colour as a property, which gives its energy (??? Q2),
3)   it also has another property: a spatial memory of the source that has emitted it (??? Q3),
4)   and so, as does the electric field that oscillates in time, it can twist it-self within the space of a wavelength, a finite number of times (??? Q4)  ( it is not clear whether he refers to the light or the electric field )
5)   and therefore, (the same) can give some other states of this degree of freedom (??? Q5).
6)   Those (states) are very useful, because they are independent states, like orthogonal colours (??? Q6)
7)   or orthogonal frequencies (??? Q7) ...the classic frequency (??? Q8) individuated by the temporal-vibration of the electromagnetic field.
8)   There are several applications... in astronomy, as we utilize light as the main information vehicle, therefore, the more information we have the more we get to know about our universe, our cosmo. An example?
9)   The most immediate application we can have is both on the detection of the black holes rotation and on the omogenity and distribution of the interstellar matter.. of the plasma. Though, there are also some more interesting applications related to the every-day life. Recently, we have also carried-out an experiment in San Marco, where we have had in use the Palazzo Ducale as the receiving station and the Compagnia delle vele tower as the transmitting station and
10)   we have succeded in transmitting two channels of radio-transmission on a wi-fi frequency, having discriminated them by their vorticity (??? Q9).
11)   Hence, the vorticities act as independent channels on the same frequency (??? Q10) and onto them it can be applied the multiplexing and the rest,
12)   allowing to multiply the number of channels as much as one would want to exploiting this principle (??? Q11).
13)   theoretically to the infinite (??? Q12), in practice (??? Q13), we can multiply by a factor of 100 (??? Q14), in a reasonable manner (ehehehehehe!), all the channels in a single band of transmission.
14)   There are also some other applications, in optics, in microscopes, in telescopes,
15)   since, utilizing this further information (??? Q15), coded by phase (??? Q16), we can augment the resolution (??? Q17),
16)   and so the capacity of seeing more details, which to date would result in being out of the sight of an ordinary microscope or telescope (??? Q18).

 

For their unsubstantiated claims the Team has come under fire from several scientists, who have adopted different approaches to the matter according to their own field of expertise.

Italian university to join the race for actively damaging the image of the scientific research in Italy!

Overwhelmingly enthusiastic boffins
managed to make a world-wide
unvoluntary hoax announcement.

Naïve theoreticians from the Department of physics and astronomy of the University of Padua and the Swedish Institute of Space Physics have covered themselves with ridicule after claiming they have found a way to force photons to follow an helicoidal trajectory in the free space, in a circular-vortex-like fashion, by simply getting a conventionally generated plain wavefront to bounce back off a portion of a purposefully distorted paraboloidal reflector (pictured below).

They have also claimed that by doing so, a number of radio carrier signals having identical frequency could travel on the same path and direction by means of circular vortex-like trajectory differing from each other only by the phase of their vortex, each carrying a different set of informations, thus obtaining more channels in the same frequency.
According to the informations I gathered, they have conducted some seriously ill-conceived and ill-deviced experiments with the assistance of a few italian radio amateurs, instead of hiring proper microwave engineers.
Owing to their lack of competence and expertise, the italo-swedish Team has blatantly failed to comprehend the results and its own mistakes. Needless to say: their "experiment" on the venetian lagoon turned out to be a fiasco!

A new type of radio transmitter, based on a general feature of waves identified by Michael Berry and John Nye in 1974, has been invented by Fabrizio Tamburini of Padova and Bo Thide of Uppsala. On Friday 24 June it was launched at a splendid though somewhat surreal ceremony in the Palazzo Ducale in Venice, culminating in a string-and-sealing-wax demonstration in which signals were sent to the Palace from a lighthouse on the other side of the Canale di San Marco.

The transmission channel uses a parabolic dish with a helicoidal deformation, that creates a wave with a phase singularity a radio-wave vortex. At the receiver, two phased antennas can distinguish this signal from one transmitted simultaneously using a conventional dish. The demonstration, which had worked perfectly all day during tests, almost failed on the night because winds misaligned the transmitter. But at the last moment, and to applause from an expectant crowd, a high note was transmitted on one channel and a low note on the other, with the discrimination between them being authenticated by hard-nosed ham local radio enthusiasts.

To physicists this is a clever trick using interference, but industrialists from the satellite broadcasting industry who were present at the ceremony saw it differently: a potentially lucrative way to double the number of channels that can be transmitted at each frequency while conserving precious bandwidth.

In this interview given to a journalist from RAI's TG-Leonardo, Fabrizio Tamburini, in an attempt to describe what he thinks they have found, talks about "drunk photons". Unfortunally, it wasn't the photons to be drunk at that time!

 

March the 8th., 2012. On this other occation, during a press conference in Cà Farsetti - Venice, Fabrizio Tamburini, states that their experiment, as carried out over the venetian lagoon, has been validated by the "European institute of physics in London". Unfortunally, there is no such an institute by that name in London, nor elsewhere!

 

Filippo Romanato on this occation claims they have produced "useful inventions". However, none of what he has envisaged has found a practical application to date, nor they have made any further attempt to demonstrate what they claim.

Filippo Romanato along with Fabrizio Tamburini, Bo Thidé and Cesare Barbieri are the named "inventors" of a "method and system of telecommunications for the broadcasting transmission and reception of electromagnetic signals" as claimed in an application for an industrial patent filed by the University of Padua at the italian patent office on June the 24th. 2011,
