Professor Andy Marvin of University of York’s Department of Electronic Engineering

Presented by Professor Andy Marvin, University of York, UK

The lecture describes the Prof. Marvin's research over the past decade
investigating better ways of defining and assessing the shielding
performance of equipment enclosures. The definition of enclosure
Shielding Effectiveness and its limitations are reviewed. Then recent
research on the use of surrogate contents to replicate real electronic
enclosure contents is described leading to alternative definitions of
enclosure shielding performance. Recently, the work has concentrated on
shielding of equipment enclosures in the microwave frequency range. Here
the reverberant nature of the enclosures is exploited and the
contribution of the Absorption Cross-sections of the enclosure structure
and contents and the Transmission Cross-sections of the enclosure
apertures to the overall Shielding Effectiveness is described.

Prof. Andy Marvin is Professor Emeritus in the University of York’s
Department of Electronic Engineering, Fellow of the Royal Academy of
Engineering, and an IEEE Life Fellow. He received his BEng, MEng and PhD
degrees in Electrical and Electronic Engineering from the University of
Sheffield in 1978. From 1977 to 1979, he was with the British Aircraft
Corporation at Filton, Bristol, UK working on antenna design and EMC. He
was appointed to a Lectureship in Electronics at the University of York
(UK) in 1979, promoted to Professor of Applied Electromagnetics in 1995,
and retired as Professor Emeritus in 2017. He was appointed as Technical
Director of York EMC Services at its founding in 1995 until acquisition
by Eurofins in 2017.

His main research interests are EMC measurement and modelling
techniques, EMC antennas and electromagnetic shielding measurement and
modelling and is the author of more than 300 papers. In 1992, he and Dr.
Stuart Porter invented the Bilog EMC measurement antenna. Prof. Marvin
was Vice-Chairman of the IEEE Std-299 Working Group on Shielding
Effectiveness Measurement that produced the IEEE Std 299.1 revision in
2013. From 1994 to 2015 he was an Associate Editor of IEEE Transactions
on EMC. He was a member of the UK National Measurement System Advisory
Panels on Innovation Research and Development and Materials and
Modelling from 2008 to 2015. He is a founder member of the International
Steering Committee of EMC Europe conferences, Conference Co-Chair of EMC
Europe 2011 (York) and Chair of the EMC Europe International Steering
Committee for 2015 – 2018.
