This project aims to develop novel terahertz polarization optics including polarizers, waveplates, and circular polarizers based on artificial birefringence metamaterials. The project will involve numerical simulations, design optimization, and potentially experimental characterization of prototype devices.

Polarization control is crucial for everything from next-generation wireless communications to biomedical imaging. At terahertz frequencies (0.1 – 10 THz), however, conventional polarizers and waveplates are often bulky, lossy, and extremely expensive.  These limitations arise primarily from two challenges. First, is the lack of natural low-loss highly birefringent materials in the terahertz range. Second, the broad terahertz bandwidth demands achromatic responses that are difficult to realize. By developing novel metasurfaces, we can make devices that are not possible with naturally occurring crystals.  

Background knowledge of electromagnetism and optics is required for this project. Experience in MATLAB and COMSOL would be beneficial.
