Research Interests: Dr. Scanlon is
Director of the Centre for Communications Engineering at the University
of Ulster (www.ether.ulst.ac.uk). His current research interests include
bioelectromagnetics, antennas, radiowave propagation, wireless networks,
and RF electronics. He has particular expertise in the area of tissue-implanted
and surface-mounted antennas and devices for personal communications or
medical and biological telemetry. Dr Scanlon also conducts independent
research and provides consultancy in the area of biological and health
effects of radiofrequency radiation.
The Lecture: Body-implanted
radio devices are being employed in a range of new medical device applications,
some operate at UHF, taking advantage of greater bandwidth, more efficient
antennas and lower levels of electromagnetic noise. Recently there has
been global agreement on the use of the 402 - 405 MHz band for ultra low
power (25 mW radiated power) medical implant use. The
widespread use of implanted UHF-radio sources does, however, present a
new problem in bioelectromagnetics — the study of the interaction
of electromagnetic fields with biological tissue. Using key examples, this
lecture will describe the measurement and modelling of body-implanted radio
sources. Issues such as health and safety concerns and how to improve radiative
efficiency will also be discussed. The lecture will be of interest to academic
staff, postgraduates and undergraduates in the area of applied physics,
electronic engineering and biomedical engineering.
