Advance brings ‘hyperbolic metamaterials’ closer to reality in Purdue News

… “Plasmonic and metamaterial devices require good material building blocks, both plasmonic and dielectric, in order to be useful in any real-world application. Here, we develop both plasmonic and dielectric materials that can be grown epitaxially into ultra-thin and ultra-smooth layers with sharp interfaces,” Boltasseva said…

Gururaj Naik was voted by Purdue ECE-Graduate Student Assoication as the Outstanding Graduate Student, 2013.
Among the ten ECE graduate students nominated for the award by ECE-GSA committee, three highest voted were chosen for the award.

Alternative Materials Could Bring Plasmonic Technologies – Purdue News Release

$This graphic depicts a device created using "negatively refracting metamaterials" that could bring advances in applications including sensing, imaging, data storage, solar energy and optics. Purdue researchers are working on a range of options to overcome a fundamental obstacle in commercializing the materials.

Researchers are working on a range of options to overcome a fundamental obstacle in commercializing “plasmonic metamaterials” that could bring advanced optical technologies for more powerful computers, new cancer treatments and other innovations.
… The researchers are working to replace silver and gold in materials that are created using two options: making semiconductors more metallic by adding metal impurities to them; or adding non-metallic elements to metals, in effect making them less metallic…[More]

OSA News Release: “Novel Plasmonic Material may merge photonic and electronic technologies”

Helping bridge the gap between photonics and electronics, researchers from Purdue University have coaxed a thin film of titanium nitride into transporting plasmons, tiny electron excitations coupled to light that can direct and manipulate optical signals on the nanoscale. Titanium nitride’s addition to the short list of surface-plasmon-supporting materials, formerly comprised only of metals, could point the way to a new class of optoelectronic devices with unprecedented speed and efficiencies.
