Patent ID: 10914866

Abstract:
Materials comprising metamaterials exhibiting form-induced birefringence and anisotropic optical properties are provided. The disclosed articles comprise structures with critical dimensions which are on the order of or smaller than the wavelength for the gigahertz and terahertz spectral range. Methods of preparing same using stereolithography are disclosed. In a further aspect, the disclosed methods pertain to spectroscopic ellipsometry methods comprising a biaxial (orthorhombic) layer homogenization approach is to analyze the terahertz ellipsometric data obtained at three different sample azimuth orientations. The disclosed articles and methods demonstrate provide an avenue to fabricate metamaterials for the terahertz spectral range and allows tailoring of the polarizability and anisotropy of the host material. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
