Abstract :

We report on developments of fabricating nano and micro-structured volumetric plasmonic materials, metamaterials and other materials with unusual electromagnetic properties, utilizing crystal growth techniques based on directional solidification and crystallization. Two types of materials will be discussed: (i) based on directional solidification of eutectic composites, and (ii) directional solidification of dielectrics directly doped with functional nanoparticles of various size, shape and chemical composition (metallic-plasmonic, quantum dots) as well as various additional elements as rare earths, obtained by the nanoparticles direct doping (NPDD). It has been shown that with self-organization mechanism during the eutectic crystallization various shapes pertinent to metamaterials can be obtained as the 'split-ring resonator' geometry, rodlike or lamellar structures which can be used as hyperbolic metamaterials, or for subwavlength transmission of electromagnetic waves, eutectic-based tunable nanoplasmonic materials have been demonstrated for the first time, as well as enhanced second harmonic generation, strongly enhanced Faraday effect and others.
