In countless fantasy or science fiction plots, invisiable is the state of an object which cannot be seen by the eyes. It can be divied into two sections, actual invisibility and virtual invisibility. The former one refers to invisibility in the pure sense, as in this state, other people can go through your body without any notice. the latter one refers to invisibility that you are invisible by sight, but can be felt or touched by others. It is reported that the 'invisitable cloak' is made of mixture of metal and circuit board materials such as ceramic or fiber composite. since particular light spectrum is absorbed by this materials, the remain light is so weak that it cannot be felt by human eyes, then object itself disappears from view as if it doesn't exist.
