New Invisibility Cloak. Not Only Invisible, But Also Inaudible. As If Nothing Was There

New Invisibility Cloak. Not Only Invisible, But Also Inaudible. As If Nothing Was There: "Progress of metamaterials in nanotechnologies has made the invisibility cloak, a subject of mythology and science fiction, become reality: Light waves can be guided around an object to be hidden, in such a way that this object appears to be non-existent. This concept applied to electromagnetic light waves may also be transferred to other types of waves, such as sound waves. "
