Negative refraction in Al:ZnO/ZnO metamaterial in the near-infrared
Gururaj V. Naik, Jingjing Liu, Alexander V. Kildishev +2
Noble metals such as gold and silver are the primary metallic building blocks of metamaterial devices. Making subwavelength-sized structural elements from these metals seriously li…
A comparative study of semiconductor-based plasmonic metamaterials
Gururaj V. Naik, Alexandra Boltasseva
Recent metamaterial (MM) research faces several problems when using metal-based plasmonic components as building blocks for MMs. The use of conventional metals for MMs is limited b…
Semiconductors for Plasmonics and Metamaterials
Gururaj V. Naik, Alexandra Boltasseva
Plasmonics has conventionally been in the realm of metal-optics. However, conventional metals as plasmonic elements in the near-infrared (NIR) and visible spectral ranges suffer fr…
Oxides and nitrides as alternative plasmonic materials in the optical range
Gururaj V. Naik, Jongbum Kim, Alexandra Boltasseva
As alternatives to conventional metals, new plasmonic materials offer many advantages in the rapidly growing fields of plasmonics and metamaterials. These advantages include low in…
