University-Industry Cooperative Research Committees
187th Committee on Metamaterials
Aims and Goals
The electromagnetic responses of normal materials are determined by microscopic arrangements of atoms and molecules that comprise them and their crystal structures. This causes significant limits in their permittivity and permeability values. However, by designing structures on a scale smaller than its wavelength and larger than its atoms and molecules, it is possible to freely control a material’s effective permittivity and permeability. Based on these, artificial materials with unique electromagnetic responses such as negative refraction and wave detouring, which had been considered impossible to fabricate, are now becoming a reality.
The Committee is working to incubate new industries by carrying out studies and engaging in intensive discussions on the development of methods to compose and fabricate metamaterials and on basic research to explore new metamaterial phenomena and their potential industrial applications.
The Committee carries forward a discussion on new concepts and standardized research methodologies needed to advance research on the application of metamaterials to industry. It is important for companies that are considering entry into metamaterial markets to estimate the present status of methods for electromagnetic field calculation, fabrication and characterization. At the present stage, we will not try to start a consortium on any particular targets. The Committee sets the following five perspectives for its research topics.
Metamaterial design Electromagnetic field calculation methods, extracting effective media parameters, transformation optics
Metamaterial functions Possible metamaterial functions, maker seeds, sub-wavelength electromagnetic field pattern formation, electromagnetic field propagation manipulation, antenna directivity control, electromagnetic wave control devices, light-emitting/light-receiving devices
Metamaterial evaluation Know-how acquision and new development of evaluation methods
Metamaterial manufacture Top-down (micromachining) and bottom-up (nano-chemistry, self-assembling) methods, higher precision and lower cost
Metamaterial applications Systems using metamaterials; consumer’s needs for metamaterials
