Thereza M. Macnamara attained her first degree in applied physics and her master’s degree in microwaves at London University. After two years of teaching physics up to Advanced level, she worked as a microwave engineer at G&E Bradley. She then worked as a research physicist for Morganite Research and Development before returning to work as a microwave engineer, working on a standard field facility, waveguide components, thermistor detectors, and calibration at Wayne-Kerr Laboratories, Flann Microwave Instruments ad Bradley Electronics. After a short break to have a family, she returned to work as an examiner at the British Patent Office and lecturing in mathematics and physics whilst her children were growing up. She then took up a post as a senior RF engineer at ERA Technology, where she worked on antennas, feed networks and as an EMC engineer, before taking up the post of an electromagnetic specialist at BAE Systems where she worked fro 17 years. Whilst at BAE Systems she worked in the R&D department and on Nimrod, Typhoon, Harrier, Tornado and Jaguar aircraft, and then became the technical coordinator of the EU funded research project IPAS (Installed Performance of Antennas on AeroStructures). Apart from many technical papers, she has also authored a reference book on EMC, entitled “Handbook of Antennas for EMC”.
