I came across this article from 2011

It says in the intro

“However, the realization of electromagnetic cloaking has both a practical and fundamental problem [34]. The practical problem is that material requirements for electromagnetic cloaking are very difficult to meet, whereas the fundamental problem is that perfect invisibility [4, 5] requires that light should propagate in certain cloaking regions with a superluminal phase velocity that tends to infinity……..Broadband cloaking based on non-Euclidean geometries was proposed in [32] to avoid the requirement for infinite light velocities for electromagnetic cloaking. In this proposal, the speed of light is finite in the entire cloaking region and, therefore, this cloak has the potential to work for a broad range of frequencies. However, the fundamental problem still remains. Since space has to be expanded to make room for the invisible region within the cloak, the implementation of this device will still demand superluminal propagation (i.e. propagation with a velocity that exceeds the speed of light in vacuum). The same is true for 'carpet cloaking' [20-26], where the velocity of light in the cloaking device must exceed the speed of light in the host material, i.e. vacuum, if such devices are to find practical applications”

If I am reading this correctly; are they implying; hypothetically-if there was someway to move light at superluminal speeds-that we could achieve “perfect”invisibility cloaking?

I now FTL motion is impossible but I was just wondering because I am also a huge sci-fi fan and always wanted to know how cloaking devices in Star Trek and Star Wars might work

Please just take this post with a grain of salt and “humor me” when answering. I know FTL is not supported by any physics but this is for my imagination

Here is the article if you need to see for yourself

They are fiction. They “work” because someone says they do, not because there is a physical basis to it.

I don’t know why I bother 😔. Nobody bothers to read
