Abstract:: A metamaterial is a material engineered to have a property that is not found in nature. They are made from assemblies of multiple unit cells fashioned from composite materials, whose extraordinary properties are determined by the artificial structure rather than the materials they compose of. Metamaterials have powerful ability to flexibly and efficiently manipulate physical fields, so that they can break through the property limitation of conventional materials to realize many novel functions and important applications. The emergence of transformation optics and its successful application in perfect electromagnetic cloak not only broaden the scope of metamaterials researches greatly, but also expand the physical field that metamaterials work in from electromagnetic field to other physical fields, such as acoustic, mechanic, thermal, chemical and static electric/magnetic fields, so that metamaterials working in nonelectromagnetic fields were developed rapidly. As a typical manipulation of physical fields, invisible cloak has drawn great attention of researchers. These physical fields have similar governing formula in the meantime vary in details, so that a series of interesting and distinctive research fields were developed about the invisible cloaks for multiple physical fields by metamaterials. In this review, we will briefly introduce the development of metamaterials, illustrate typical approaches for the design of invisible cloaks, and review strategies and applications of various invisible cloaks in different physical field, especially nonelectromagnetic fields.
