Title: Sensing Using THZ Radiation PART-1
Author: Michael Shur
Affiliation: Rensselaer Polytechnic Institute, USA
Abstract: The emerging application of sub-THz and THz technology for 6G communications (including future 6G Wi-Fi) has focused attention on the THz sensing and detection technology. This tutorial will cover
THz detection for 6G communications (in sub- THz and THz atmospheric windows)
THz sensing of biological and chemical hazardous agents
THz cancer detection and other medical applications
THz homeland security applications
THz sensing in radioastronomy and space research
THz sensing for industrial control
THz scanning detection for VLSI yield and reliability control
THz scanning for hardware cyber security.
The overview of the THz sensing technology will include the state-of-the-art THz sources. These sources range from traditional pulsed THz sources and frequency multipliers using IMPATT and Gunn diodes to Quantum Cascade lasers and THz plasmonic arrays. I will then discuss the THz detectors including emerging Si, III-V, III-N, and graphene plasmonic TeraFETs and spectroscopic and line-of-sight vector THz detection. The THz detection for 6G communications in the 300 GHz range could be implemented using Si CMOS with the 20 nm SOI technology node being a prime candidate for this application.
