Projects:2019s2-21501 Terahertz Waveplates
The project is to learn knowledge of terahertz technology, wave plate, CST software. And in this project we aim to design, simulate and test a wave plate operating at a frequency between 0.1 to 10 THz.

Introduction
The terahertz range spans 0.1 and 10 THz. It defines a transition between the electronics and photonics domains—the frequency range is at the upper bound of electronics and the lower bound of photonics. For this very reason, in the past the band has been perceived as a terahertz gap due to the lack of efficient generation and detection approaches. Over a few decades, a myriad of sources and detectors have become mature to tap into unique opportunities in this frequency range. Much has yet to be done in this area towards integrated high-performance platforms, envisioned for post-5G applications. Core components that underpin any integrated platform are interconnects, i.e., waveguiding structures. A large number of terahertz waveguides have been proposed with different trade-offs related to bandwidth, dispersion, confinement, losses, and fabrication complexity. Here we will investigate a waveguide design that could carry terahertz waves with practical performance. This project will tackle on different waveguide designs and related components. The students will gain experience on full-wave electromagnetic simulation, theoretical analysis of waveguides, and a terahertz measurement system.
