Abstract

In this seminar, Prof Vardaxoglou will introduce the concept and uses of Meta-Atoms in Electromagnetic metamaterials. 3D-printed multi-layered metamaterials with different periodicities of the metallic rectangular meso scale cuboid inclusions, termed here as meat-atoms. Potentially these meta-atoms could be varied in constitution and geometry to augment a variety of artificial magnetodielectric properties. The periodicity indicates the spaces between adjacent elements. The effect of the space on the effective EM properties is examined by placing the 3D-printed samples in a waveguide or on a resonator. Some of these structures have been applied in engineering applications such as antennas and microwave lenses.

Biography

Yiannis C. Vardaxoglou is a Chartered Engineer, Fellow of the Institution of Engineering and Technology (FIET), Fellow of the Royal Academy of Engineering (FREng) and fellow of the Institute of Electrical and Electronics Engineers (FIEEE). He was the Head and the first Dean of the Electronic, Electrical and Systems Engineering School at Loughborough University from 2006 to 2012. He established the Wireless Communications Research (WiCR) group at Loughborough University and founded the Centre for Mobile Communications Research. He has served as a consultant to various industries, holds 5 patents and is the Technical Director/Founder of Antrum Ltd (a University spinout company). He has attracted research funding from industry and has been awarded 20 EPSRC/EU research grants. He has published over 250 refereed journals and conference proceeding papers and has written a book on FSS. He is past the Chairman of the Executive Committee of the IET’s Antennas and Propagation Professional Network in the UK and he chaired for 5 years the IEEE’s distinguished lecturer program of the Antennas and Propagation Society. He is a member of the EPSRC College in ICT and chaired the Executive Committee of Metamorphose, the EU FP6 NoE on Metamaterials. He was the General Chair of EuCAP’2007. He has chaired numerous IEE/IET events and has been in the Steering Committee of the IEEE International Conferences on Antennas and Propagation and EuCAP’2006. He founded and is the Series Chair of the Loughborough Antennas and Propagation Conferences (LAPC), which has been running since 2005.

  

He has pioneered research, design and development of frequency selective surfaces (FSS) for communication systems, Metamaterials and low SAR antennas for mobile telephony and has commercially exploited a number of his innovations.
