All-dielectric tunable zero-refractive index metamaterials based on phase change materials

Reviews on Advanced Materials Science, 2023
We propose a tunable all-dielectric zero-index metamaterial based on phase change material. By constructing the alternating rod structure with phase change material and silica material, the zero-refractive index characteristic is realized.

Optical Characterisation of RF Sputter Coated Palladium Thin Films for Hydrogen Sensing [PDF]

, 2011
We investigate the optical properties of Pd thin films of the thickness 20-100nm deposited on Si wafer via RF sputter coating. The Pd samples are characterised using white light interfermometry for thickness and ellipsometry for refractive index.
