Cloak of invisibility

A protective cap (from old German Tarni, " secret " ) is a mythical object to allow its wearer to make himself temporarily invisible ( conjure away ).

Stealth in mythology

Siegfried wins in the Nibelungenlied the stealth of a dwarf named Alberich guards the treasure of the Nibelungs. In the Nibelungenlied, the invisibility cloak is not a hat, but - according to the early medieval German language - a coat or cloak, the Cappa (see Cape). In today's Nibelungen representations or adaptations that stealth is almost always misrepresented as helmet.

King Laurin uses stealth to take part in an unseen Maifahrt to which he was not invited to his frustration.

A helmet that gives its wearer invisibility, the Cyclops of Greek mythology, the god of the underworld Hades finished so he can stand by Zeus in the battle against the Titans.

Another stealth Perseus is presented on its way to the Gorgon Medusa by the nymphs or Perseus takes them from the Graeae, which he has previously outwitted.

Stealth in the art

Currently, research is being conducted on a real stealth technology and worked. A stealth prototype has been completed. So-called metamaterial is utilized, having a negative refractive index and scattering of electromagnetic waves, rather than bundling them.

In addition, various methods are being developed for light refraction, direct the light through special nanotubes or crystals around the object to be camouflaged so that it can not be detected due to lack of reflection in the visible range.
