Metastructures: From Physics to Application
In recent years, there has been a growing interest in realizing artificial metasurfaces and metamaterials that provide novel and on-demand physical properties. Such metastructures can be designed on a variety of physical platforms to enhance or modify the interaction with wave species, including electromagnetic, acoustic, mechanical, spin and matter waves. These developments have engaged distinct but related communities, not only by introducing new wave physics phenomena arising from intriguing properties of such artificial structures, but also by a wide range of new potential applications. This research field is at a historical juncture as it has become the necessary platform to study and emulate novel concepts introduced through other disciplines- for example, quantum field theory and topological physics. We find it a timely opportunity for the community to bring together recent scientific and technology based discoveries in this Special Issue Collection on the physics and applications of wave interaction with metastructures.
