14 DAY TRIAL // Anyone wondering how long it will take for a true cloak of invisibility to be created, should probably start to accept that it will take a long time, but that does not mean progress isn't being made.
It may just be that a new method of making something invisible, or at least simulating invisibility, has been found.
Previous attempts at “cloaking” items tried to make use of the refraction effect, the goal being to guide light around an object.
This new technique does something else, namely “deceive” the light into creating a “photo negative image” of the object being hidden.
It is said that success has already been experienced with the new procedure, though it has a fairly big limitation right now.
While the “negative image” was surely enough created, it was only able to fool the microwave spectrum.
It also bears noting that this is not a flexible solution, not as much as the one reliant on bouncing light around.
After all, the “cloaking field” has to be specifically tailored to the object whose invisibility is sought.
For those who want more technical details, the breakthrough used plasmonic materials to play this trick of the light.
In comparison, the other ideas for invisibility rely on metamaterials for deflecting and guiding light from one point to another.
There is no telling how long it will take for invisibility to be achieved on the entire electromagnetic spectrum (EM).
Verily, that feat may never actually be achieved. Fortunately (or sadly, depending on who you ask), it is not exactly necessary for most spies or thieves either. All anyone could ask for is that an invisibility technology shield something, or someone, from the segment of light that human eyes can see.
Alas, that is a daunting task all on its own. Nevertheless, with humanity's hopes so high because of all Science Fiction books and films, it is a given that research will continue.
