THz electronics opens up the spectrum from a few hundred GHz to about 1 THz, enabling high resolution sensing and high bandwidth communications. These will generate true mass market applications. Micromachining technologies applied to waveguiding structures and travelling wave tubes, and continual advances in semiconductor devices, are enabling the extension of mm-wave circuits upwards in frequency. Important applications are emerging, for example: high resolutionimaging radar for autonomous platforms, and the development of high data rate wireless communications, which will continue to be vitally important well beyond 5G and the Internet of Things.

This workshop explores several aspects of THz electronics. Part 1 will focus on technology, showing how guided wave structures, interconnects, antennas and active circuits are realised and integrated on semiconductor substrates and micromachined waveguiding structures. The extension of TWTA technology into THz bands and the technology and application of resonant tunnelling diodes are also covered as examples of emerging active components. Part 2 considers applications in low THz radar and wireless communications, and concludes with discussion of the low THz measurement challenges.
