Graphical representation of a metasurface

In this research project we are developing terahertz (THz) metamaterials with frequency-domain modulating functionality for THz spectroscopy. Being situated between infrared light and microwave radiation, the absorption of THz rays in molecular and biomolecular systems is dominated by the excitation of intramolecular and intermolecular vibrations. This indicates that THz technology is an effective tool for sensing applications. The design of the metamaterials is performed utilizing COMSOL finite element method based analytical modeling and fabricated using a novel Laser-based Metasurface Fabrication (LMF) method. The relationship between the filter design and bandpass characteristics are determined through THz spectrometer. 

Collaborator on the project includes Professor Hongtao Ding. Funded by ITI's Research Initiative Seed Program's Genesis grant.
