Acoustic metamaterials are artificially fabricated materials designed to control, direct, and manipulate sound waves as these might occur in gases, liquids, and solids.
One of the most intriguing properties of optical metamaterials formed from conducting or semiconducting materials is their ability to localize and enhance optical fields at selected “hotspots” within the metamaterial structure.
With metamaterials, unusual and extraordinary material properties can be created and manipulated with unprecedented flexibility and control. To harness these emerging capabilities, a new methodology was needed that would enable the rapid design of devices based on these complex materials.
Very thin layers of patterned metamaterials can be used to create unique low-profile, flat, optical devices, such as lenses, filters and other optical components.
Passive metamaterials, while still able to create many exotic effects, are limited by losses and constrained bandwidth due to their constitutive structures.
Metamaterials are composite electromagnetic materials that enable the development of new imaging modalities in the long-wavelength regime.
Emitters of light such as molecules and semiconductor quantum dots have relatively long emission lifetimes (~10 ns) and non-directional emission.
Remote powering of devices is fast becoming one of the most important technological pursuits in engineering.
Metamaterials can be used to form a unique imaging device, capable of forming images without moving parts or arrays of detectors.
