The strong resonant interaction of plasmonic particles with light has been used in a wide range of applications in recent years. The high sensitivity of the coupling between plasmon resonances to the interparticular distance between neighboring particles offers a powerful tool to tune their optical properties. More recently, the discovery that specific geometries of groupings of nanoparticles, or plasmonic nanoparticle clusters, can generate remarkable optical properties such as optical magnetism has motivated the development of new fabrication techniques. Such clusters could serve as building blocks in a new generation of self-assembled metamaterials. In this article, we describe the geometries, fabrication techniques and optical properties of symmetric clusters of plasmonic particles.Read less <
