Progress in the Terahertz region of the spectrum is now such that real engineering applications can be discussed. A large bandwidth is available, unlike X-rays, etc. it is safe for humans and non-destructive. However the radiation is absorbed by water and so not useful for long distance transmission. It may be approached as extending the r.f. spectrum upwards or extending the optical spectrum downwards. 0.3 to 3 THz is also called the submillimetre waveband, and above that is called ‘super THz’. CMOS devices are moving up into the THz range, and applications being found in non-destructive testing and in weapons and security. It is possible to use FET techniques to generate THz frequencies or else two optical frequencies may be mixed in a non-linearity and the THz difference frequency extracted.
After working in industry as a satellite systems engineer for maritime and military communications, he spent 12 years developing microwave and millimetre-wave integrated circuit technologies at King’s College London and University of Surrey. He moved to Imperial College London in 2001 and worked on microelectromechanical systems, wireless power transfer and, more recently, terahertz and ‘Over the THz Horizon’ thermal infrared technologies. He has authored approximately 200 papers and 12 book chapters and delivered many Plenary and Keynote presentations at international conferences. He was an IEEE Distinguished Microwave Lecturer from 2010 to 2013, and has been a EuMA European Microwave Lecturer since 2013. He is a Fellow of the IoP (UK, 2005), IET (UK, 2005), the Electromagnetics Academy (USA, 2008) and IEEE (2014). In Apr. 2014, he co-founded the Imperial College London spin-out company Drayson Wireless Ltd.

The meal in Savoy Place will be available for a group price of £16.95 per person including wine.
The lecture qualifies for 1½ CPD hours
Visitors are recommended to arrive early enough to allow time for the security check-in procedures; lunch must be paid for in the Faraday Kitchen (level 2) before the meal. The lecture is expected to be in the Mountbatten Room (level 2), the lunch might be in the Riverside Room (level 3):
These Friday afternoon lunch / lecture events are held approximately every month
