14 DAY TRIAL // I'd love to say that scientists have finally invented an invisibility cloak, or cloaking field or whatever, but that is not the case.
Rendering an item invisible to the perceivable light spectrum hasn't been achieved yet, except in very small proportions.
Shielding items from microwaves, however, has been achieved, to the point where anyone can do it.
Or at least, to the point where anyone with a 3D printer and access to the latest breakthrough from Duke University can do it.
Long story short, engineers from Duke have used 3D printers to create an obscuring device that can be made in just a few hours.
Shaped like a hole-covered disk, it determines, through various algorithms, where holes in the plastic pattern should be in order to deflect microwave beams.
More on this in the online journal, Optic Letters.
