Invisibility Cloak

An invisibility cloak is a device or material designed to make objects or people less visible or seemingly disappear by bending light around them. This is often achieved through advanced materials called metamaterials that manipulate electromagnetic waves. When light passes through or around the cloak, it is directed in such a way that the object behind it remains hidden from view. While true invisibility cloaks are still in experimental stages, they represent a fascinating intersection of physics and engineering with potential applications in defense, privacy, and optical technologies.
