Abstract. This article discusses fundamental properties of metamaterials. Firstly, it is argued that the defining property of metamaterials is emergence and not that they should display properties not observable in nature. In addition, the regime where matter can be assigned effective properties will be quantified using concepts of metamateri-alization period and number of generations. Keywords Metamaterials, complex materials, artificial media, emergence, nanotechnology, metamaterialization period. 1.

Meta-material is a word made of two parts; 'meta' meaning beyond and 'materials'. They are materials engineered to exhibit properties which are not found in nature. They are made from assemblies of multiple elements fashioned from composite materials such as metals and plastics. The structural elements of these materials are arranged in repeating as well as non-repeating patterns. Meta-materials derive their properties from the base metal i.e., chemical composition as well as from their newly designed structures. Their precise shape, geometry, size, arrangement and orientation give them their smart properties capable of manipulating, absorbing, enhancing as well as bending waves ranging from acoustics to electromagnetic waves to achieve benefits that go beyond what is possible with conventional materials. Metamaterial research is an interdisciplinary field and involves various engineering domains such as electrical engineering, mechanical engineering, material science, solid state physics and more. Potential applications of metamaterials are diverse and include optical fibres, medical equipment, sensors as well as military operations and aerospace applications.

Metamaterials: Reshape and Rethink
Engineering, 2015
Metamaterials are composite materials whose material properties (acoustic, electrical, magnetic, or optical, etc.) are determined by their constitutive structural materials, especially the unit cells. The development of metamaterials continues to redefine the boundaries of materials science. In the field of electromagnetic research and beyond, these materials offer excellent design flexibility with their customized properties and their tunability under external stimuli. In this paper, we first provide a literature review of metamaterials with a focus on the technology and its evolution. We then discuss steps in the industrialization process and share our own experience.

Metamaterials provides the possibility to synthesize artificial media with the properties not found among natural materials and thus able to open up new fields of application or to improve the existing ones. This paper provides a review in which, firstly the concept of metamaterials in its historical context is given. We then overview its main properties in demonstrating some of the most striking and unusual phenomena, and attempt to assess their real potential towards practical implementations.

Multifunctional composites: a metamaterial perspective
Multifunctional Materials
Multifunctional composites offer the ability to increase the efficiency, autonomy and lifespan of a structure by performing functions that would have been considered by designers as mutually exclusive. In the present perspective paper, a subclass of multifunctional composites is considered: metamaterials. In this perspective, a multifunctional composite is defined as ‘made of two or more materials that perform two or more functions in a manner that is constructive to the overall purpose of the structure’ where there is no differentiation between structural or non-structural functions. Equally, we define metamaterials are a class of man-made structures that display properties that are opposite to those typically found in nature. These ‘engineered’ architected materials continue to revisit and extend the boundaries of traditional materials science, opening up a wealth of new opportunities impacting on all aspects of human life. In our work, multifunctional metamaterials are delineated...
