Investigations Into 1D and 2D Metamaterials at Infrared Wavelengths
MEMS and Nanotechnology
Investigations are made into the characterization of 1D metamaterials consisting of stacks of metal and dielectric. These stacks are modeled and designed to have a permittivity approaching zero. Simulation, fabrication and testing are conducted to verify the design of the layered material. These stacks are fabricated using magnetron sputtering and tested using Fourier Transform Infrared Spectroscopy (FTIR). Comparison between modeled and measured reflection and transmission are used to determine if the fabricated structure is behaving like a homogeneous material. Collected results indicate that a homogeneous structure was structures were formed, one with a possible low permittivity.
