A metamaterial (from the Greek word μετά meta, meaning "beyond" or "after", and the Latin word materia, meaning "matter" or "material") is a type of material engineered to have a property, typically rarely observed in naturally occurring materials, that is derived not from the properties of the base materials but from their newly designed ...
In sociology, a social system is the patterned network of relationships constituting a coherent whole that exist between individuals, groups, and institutions. [1] It is the formal structure of role and status that can form in a small, stable group. [1]
SEM image of a pentamode metamaterial (with a size of roughly 300μm) A pentamode metamaterial is an artificial three-dimensional structure which, despite being a solid, ideally behaves like a fluid. Thus, it has a finite bulk but vanishing shear modulus, or in other words it is hard to compress yet easy to deform.
Traditionally, concepts employed to study technology use at the workplace were adopted from advancements in philosophy and sociology, such as contingency theory, structuration theory and actor-network theory. However, sociomateriality is the first concept to be developed within the field of Information System (IS) studies, a division of ...
A nonlinear metamaterial is an artificially constructed material that can exhibit properties not yet found in nature. Its response to electromagnetic radiation can be characterized by its permittivity and material permeability .
A metamaterial which produces a negative index of refraction.The total array consists of 3×20×20 unit cells with overall dimensions of 10×100×100 millimeters. The history of metamaterials begins with artificial dielectrics in microwave engineering as it developed just after World War II.
Auxetic metamaterials are a type of metamaterial with a negative Poisson's ratio, so that axial elongation causes transversal elongation (in contrast to an ordinary material, where stretching in one direction causes compression in the other direction). Auxetics can be single molecules, crystals, or a particular structure of macroscopic matter ...
Examples include study groups, sports teams, schoolmates, attorney-client, doctor-patient, coworkers, etc. Cooley had made the distinction between primary and secondary groups, by noting that the term for the latter refers to relationships that generally develop later in life, likely with much less influence on one’s identity than primary groups.
