Metamaterials can be integrated with optical waveguides to tailor guided electromagnetic waves (meta-waveguide). [110] Subwavelength structures like metamaterials can be integrated with for instance silicon waveguides to develop and polarization beam splitters [ 111 ] and optical couplers, [ 112 ] adding new degrees of freedom of controlling ...
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 .
Diffusion metamaterials [1] [2] are a subset of the metamaterial family, which primarily comprises thermal metamaterials, particle diffusion metamaterials, and plasma ...
[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 ...
Electronic mechanical metamaterials [67] are active mechanical metamaterials with digital computing and information storage capabilities. They have built the foundation for a new scientific field of meta-mechanotronics (mechanical metamaterial electronics) proposed in 2023. [ 67 ]
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 ]
Quantum metamaterials apply the science of metamaterials and the rules of quantum mechanics to control electromagnetic radiation.In the broad sense, a quantum metamaterial is a metamaterial in which certain quantum properties of the medium must be taken into account and whose behaviour is thus described by both Maxwell's equations and the Schrödinger equation.
A negative-index metamaterial causes light to refract, or bend, differently than in more common positive-index materials such as glass lenses.. Negative-index metamaterial or negative-index material (NIM) is a metamaterial whose refractive index for an electromagnetic wave has a negative value over some frequency range.
