Studies of surface plasmons and localized surface plasmons at terahertz frequencies
(2009-12)
Scope and Method of Study: The goal of this study is to investigate the physical mechanism of field enhancement in plasmonic subwavelength structures in the terahertz regime. Such plasmonic structures were fabricated by ...
Terahertz diffuse reflectors and their effects on group delay dispersion and communication performance
(2021-12)
Engineered terahertz diffuse reflectors were created using mixtures of paint and varying amounts of aluminum powder to improve the reflectivity and scattering properties of surfaces. The performance of these reflectors is ...
Manipulating terahertz radiation using novel metamaterials towards functional passive and active devices
(2012-07)
Scope and Method of Study: The objective of this study is to explore the fundamental physics in novel metamatrials functioning in THz region, and to develop passive and active functional devices, such as filters, ...
Terahertz metamaterials: Refractive index, sensing, and resonances
(2021-07)
Engineering of high refractive index metamaterials at terahertz frequencies have been presented. Applications of terahertz metamaterials as sensor and polarization convertor have also been introduced. The metamaterials ...
Group velocity dispersion management in terahertz wireless communication channels
(2020-05)
High-fidelity models of the atmosphere from 0.1 to 1 THz based on spectroscopic databases are used to examine the effect of group velocity dispersion on ultra-wideband THz links. Previous spectroscopic characterization of ...
