Further Comment on 'Encoding many channels on the same frequency through radio vorticity: first experimental test'

TL;DR

This paper clarifies that Tamburini et al.'s reply does not address or invalidate the concerns raised in the authors' initial comment regarding their experiment on encoding multiple channels using radio vorticity.

Contribution

The paper provides a critical analysis showing that the recent reply fails to resolve the issues previously highlighted in the experimental study.

Findings

Tamburini et al.'s reply does not invalidate the original concerns

The original issues raised remain unaddressed

The debate on radio vorticity encoding continues unresolved

Abstract

We show that the reply by Tamburini et al (2012 New J. Phys. 14 118002) to our previous comment (2012 New J. Phys. 14 118001) on the experiment reported in (2012 New J. Phys. 14 033001) actually does not invalidate any of the issues raised in our initial comment.
