Abstract:
1. A tunable metamaterial structure comprising a membrane having an area that is subdivided into a plurality of strips each extending continuously in a first dimension between a first end support and a second end support, wherein at least a subset of the strips is elastically deformable so as to permit motion of substantially the whole strip between the first end support and the second end support, with neighboring strips being spaced apart in a second dimension by gaps, wherein the area hosts a metamaterial formed by an array of metamaterial elements which at least partially cover the area of the strips and define a plurality of lattice parameters of the metamaterial, and wherein at least selected ones of the elastically deformable strips are shaped and dimensioned to permit their motion in response to a control parameter, thereby to cause neighboring strips to move relative to each other in a way that is substantially translation relative to each other and thereby perturb at least one lattice parameter of the metamaterial.
