Metamaterials are under consideration for many applications. [83] Metamaterial antennas are commercially available. In 2007, one researcher stated that for metamaterial applications to be realized, energy loss must be reduced, materials must be extended into three-dimensional isotropic materials and production techniques must be industrialized ...
Metamaterial cloaking is the usage of metamaterials in an invisibility cloak. This is accomplished by manipulating the paths traversed by light through a novel optical material. Metamaterials direct and control the propagation and transmission of specified parts of the light spectrum and demonstrate the potential to render an object seemingly ...
Metamaterials Handbook is a two-volume handbook on metamaterials edited by Filippo Capolino professor of electrical engineering in University of California. [1] [2] The series is designed to cover all theory and application topics related to electromagnetic metamaterials. Disciplines have combined to study, and develop electromagnetic ...
[6] [7] In metamaterials, cells take the role of atoms in a material that is homogeneous at scales larger than the cells, yielding an effective medium model. [3] [4] [8] [6] [9] Some photonic metamaterials exhibit magnetism at high frequencies, resulting in strong magnetic coupling. This can produce a negative index of refraction in the optical ...
The history of metamaterials begins with artificial dielectrics in microwave engineering as it developed just after World War II. Yet, there are seminal explorations of artificial materials for manipulating electromagnetic waves at the end of the 19th century. [ 1 ]
Diffusion metamaterials [1] [2] are a subset of the metamaterial family, which primarily comprises thermal metamaterials, particle diffusion metamaterials, and plasma diffusion metamaterials. Currently, thermal metamaterials play a pivotal role within the realm of diffusion metamaterials.

Metamaterials are artificial materials engineered to provide properties which may not be readily available in nature. These materials employ the inclusion of small inhomogeneities to enact effective macroscopic behavior. The primary research in metamaterials investigates materials with negative refractive index.
