Ah yes, invisible cloaks!
I keep covering this, in the hope the technology will finally mature at some point.
There’s loads of technologies to choose from
Now, the metamaterias gang has produced a cloak measuring 10 x 50 cm It bends waveforms in a large range of frequencies and is very low loss.
They’ve developed software which allows them to very quickly prototype the placement and layout of the metamaterials over a surface. The technology itself is fairly cheap to implement. So it looks like it’s finally happening for real!
