Projects:2019s1-176 Terahertz Waves for Imaging and Radar Cross Section Measurement

Introduction

Project description here

Abstract

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.
