Expert witness services  for matters relating to the siting of mobile radio base stations,  the investigation of engineering failures and personal accidents, and planning matters involving telecommunications equipment.

RADHAZ (ICNIRP, CEMFAW) Having worked with antennas for more than 50 years, including many high power radio and TV broadcast systems, I have good reason to keep up to date with research on the possible health effects of EM fields on the human body. I provide advice to clients regarding ICNIRP compliance of mobile radio base stations, and measurement services and expert witness services when needed. 

Patents Expert witness services in patent litigation, extensive experience in drafting patents, searching for prior art and responding to Examiners' search reports. My own patents are listed here.

World Wide Experience  I regularly work overseas and have completed projects for clients in many countries. This link lists countries I've worked in.

Measurement facilities    I have my own network and spectrum analysers and use a recently installed ETS-Lindgren 3-D chamber for the measurement of antenna patterns, efficiency, and the active performance of radio devices in the band 400 MHz–6 GHz.

Computer simulation   I currently use CST Microwave Studio and NEC-4 as my electromagnetics simulation tools.

I am currently a consultant member of the QMUL team working on Space Based Solar Power Systems.

Personal career history   For many years I was Technical Director at CSA Ltd (Rochester, UK), leading the engineering team on the design, manufacture and installation of antennas for broadcasting, communications and military applications. From 2003-2012, I was Chief Applications Engineer at Antenova Ltd, (Cambridge, UK) where I designed small antennas for a wide variety of devices, including handsets, payment terminals and GPS trackers.

Since 2002 I've provided a wide range of consultancy and design services,  and have now completed more than 240 projects. I will be happy to provide references on request.

Languages  Je parle français et j'ai réalisé des projets sur site en France et dans autres pays francophones.
