 Paragraf;  Queen Mary University of London
Atomically thin planes of carbon atoms, graphene, were isolated in 2004, and the two discoverers received Nobel Prizes. Graphene flakes and powders are being increasingly used in car tyres, paint, concrete, running shoes, tennis racquets, etc. However, widespread manufactured graphene electronic devices do not exist because of the lack of high-quality large-area graphene.
This talk will introduce our next-generation large-area graphene, which is free from metallic contamination and transfer problems, and can be produced on a variety of substrates (sapphire, Si, GaN, etc.). The first proof-of-concept product made from this graphene, a magnetic Hall-effect sensor will be described. The potential of our next-generation graphene for THz applications will be discussed.

5G mm-Wave Antennas for Mobile Terminals
Antennas for mobile terminals have been receiving considerable attention in recent years because of their wide applications in mobile phones, tablets, laptops, smart watches and body centric sensors. Over the years, the antenna design for mobile terminals has become increasingly difficult and challenging, especially for mobile terminals with metallic industry design (ID). This is mainly attributed to more and more frequency bands, carrier aggregations (CA) and MIMO requirements. A typical smart phone should now have a large number of antennas, including 2G/3G/4G/5G Sub 6GHz antennas, GPS antennas, WiFi antennas, MIMO antennas and a NFC antenna. For mobile terminals of the 5th generation mobile communication, which aims mm-Wave frequency bands and has much higher capacity, the antenna design is even more complex and challenging. The major problems and challenges could be classified as:
(a) Co-exist with 2G/3G/4G/5G Sub 6GHz antennas;
(b) Very limited antenna volume and restricted antenna location;
(c) High requirement of EIRP;
(d) 360 degree of beam-forming radiation coverage;
(e) Severe impact of human body and hands on antennas’ performance, including radiation pattern, bandwidth and efficiency/EIRP.
In this talk, all the above challenges and possible solutions will be addressed.

Mr. David R. Vizard
Co-founder of VivaTech SARL France
Title: Vector Network Analyzer Extenders for the Low THz Range ; New Configurations and Recent Applications
The Low THz spectrum has potential for high resolution imaging applications such as automotive radars and high data rate communications. Propagation studies and test platforms require compact portable equipment which may be achieved by extending the frequency range of commercial battery powered vector network analyzers (VNA). The development of both desktop and portable 110-670 GHz VNA based extenders is described along with some recent experimental test data using these instruments.
David R. Vizard (Date of Birth: March 10th 1950, Belfast, United Kingdom) obtained a BSc degree in electronics from the University of Manchester Institute of Science and Technology (UMIST) UK in 1971 and first worked for Marconi Communication Systems, UK designing high linearity receiver front-ends. In 1972 he joined the Radio Research Station, Slough, UK, where he developed millimeter-wave solar astronomy and low noise cryogenic receiver technologies for astronomy and space-borne applications. At age 28 he was promoted to the rank of Senior Scientist, the youngest ever to reach this position within the UK Scientific Civil Service, and then relocated to the newly formed Rutherford Appleton Laboratory.
From 1978 he worked at the UK’s Science Research Council Rutherford Laboratories, Oxford, UK, subsequently leading the Millimetre Wave Technology Division, which provides radio astronomical and atmospheric science spaceflight hardware in support of a number of space programs. These included the UK’s Meterological Satellite AMSU-B at 89-183 GHz and a first prototype of ESA’s MeteoSat covering 20-200 GHz. During 1982- 86, when seconded to NASA-JPL, USA, he designed, developed and completed the successful integration of the world’s first space-borne 183 GHz radiometer launched by the Space Shuttle as part of the Upper Atmosphere Research Satellite (UARS) payload.
From 1986, he took on the role of Technical Manager at Farran Technology Ltd, an emerging Irish mm-wave start-up company. Later, becoming a founding Director he was instrumental in the growth of the company’s turnover from less than 400 K Euro p.a. to a peak of 3.5 M Euro. During this time, he directed Farran’s product development in numerous areas including passive imaging, space flight radiometers, millimeter-wave frequency extenders, and Enhanced Flight Vision System (EVS) radars using FMCW technologies. Farran developed a number of leading edge mm-wave products including imaging systems and was purchased by Smiths Detection (USA) in February 2005.
In 2006 he co-founded VivaTech SARL France, a design and manufacturing company specializing in custom developments in the mm-wave and THz range, for a wide range of global customers. VivaTech SARL enjoys privileged R & D funding from the French Government and apart from its manufacturing activities has consulted for various top tier Companies and Universities such as Thales Optronics S.A., Hong Kong City University amongst others. VivaTech has a wide range of global clients in many sectors where the use of mm/THz technology is of key importance.
