Could “Supralight” effectively allow perfect cloaking?

[BadScientist]

I came across this article from 2011

https://dx.doi.org/10.1088/1367-2630/13/8/083007

In the introduction-it talks about the difficulties of electromagnetic cloaking and went so far as to say that it is difficult to achieve WITHOUT Superluminal propagation to infinity. This is NOT the right takeaway but I had a thought experiment and wanted to know. Theoretically, if we had access to Superluminal “energy”-would another potential application of FTL be perfect cloaking? I wanted to see if I interpreted the worded implication properly. I am also well aware that faster than light particles are basically non-existent

Reading just the Intro of the paper would suffice to see what I am referring to

I know I can't shoehorn real physics into incredibly speculative stuff, but I was just asking if I got the jist of what was said

I know I'm hardly the one you want to hear from but I find it weird that they have to stress that they want to achieve cloaking without using superluminal propagation. I mean as if that was a possibility to start with?!

I seem to remember some success were had with bending light around an object but that was surely either an April 1. joke or some extremely optimistic "researcher" who "solved" Einstein's equations in the "wrong direction" (I mean like Alcubierre and his "warp drive").

Honestly, there is only one practical solution to cloaking...
