Nanochemistry and self-assembly routes
to metamaterials for visible light
METACHEM is the acronym of the FP7 “Cooperation” small scale focused research project “Nanochemistry and self-assembly routes to metamaterials for visible light”. It belongs to the ‘Nanosciences, Nanotechnologies, Materials and new Production Technologies (NMP)’ theme in the research area NMP-2008-2.2-2 "Nanostructured meta-materials".
METACHEM was launched on 2009 September 15th for 48 months. Its total EC funding is 3.7 million €.
The goal of METACHEM is to fabricate new generations of metamaterials at infrared and optical frequencies, based on the use of nano-chemistry and self-assembly of materials.
Nano-chemistry is able to finely engineer and synthesize resonant nano-objects based on nanoparticles.
Self-assembly, well known in soft condensed matter physics, designates processes in which individual objects spontaneously organize under the effect of complex pair interactions into highly organized two-dimensional (2D) or three-dimensional (3D) structures of various symmetries.
The targeted new properties are artificial optical magnetic and dielectric properties, optical left-handed materials, near-zero permittivity/permeability; negative index materials and low-loss plasmonic structures. Applications based on optical properties are foreseen as perfect (aberration-free) lenses, hyper lenses (offering sub-wavelength optical resolution), waveguides (for opto-electronics, low-consumption lighting, etc) and more
