2019s1-176 Terahertz Waves for Imaging and Radar Cross Section Measurement
Project description here
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.This project is divided into two interrelated parts:
- One unique property of terahertz waves is their ability to penetrate dry & non-metallic materials such as clothes, plastics, cardboards, and ceramics. Therefore, terahertz imaging can yield extra information of a subject at millimetre resolution. Here, we will employ terahertz imaging to tackle an important issue in cattle livestock farming. The students will gain experience in a terahertz imaging system.
- Another potential application is stand-off seeing-through radar detection for security purposes. Weaponry or contraband hidden under cloth could be detected from afar without involving harmful X-ray radiation. This project will embark on measuring the monostatic radar cross section of knives and guns at the frequency range of 220-330 GHz where the atmospheric absorption is relatively low. The project will establish a knowledge base for future development of terahertz radar.
