WebThe concept of tensegrity is understood in many ways. This term is often improperly used for structures that have some, but not necessarily the key, tensegrity properties. The concept of tensegrity systems is misused in reference to both mathematical models and completed engineering structures.

En physique, en électromagnétisme, le terme métamatériau désigne un matériau composite artificiel qui présente des propriétés électromagnétiques qu'on ne retrouve pas dans un matériau naturel. Il s'agit en général de structures périodiques, diélectriques ou métalliques, qui se comportent comme un matériau homogène n'existant pas à l'état naturel. Il existe plusieurs types de métam…
Webmetamaterial definition) properties can be observed as the spatial sensing scale is increased. If new properties appear when the focus of sight is changed to a two times coarser resolution, the metamaterialization process is certainly much more efficient than in the case of plain Swiss rolls. This concept, scale, seems to be a very crucial notion.
