Qualifications

Dipl–Ing (German BEng (hons) equiv.), PhD

About

Jürgen Richter received his Dipl-Ing from the Department of Electronics at the Polytechnic of Hanover (Germany) in 1989 and his PhD in radiowave propagation from the University of Glamorgan in 1998. He is now a senior lecturer at the University of Glamorgan in Pontypridd He has been involved with studies of many aspects of radiowave propagation initially starting with projects on site shielding and vegetation at microwave and millimetre wave frequencies. In recent years he has been working adapting the Theory of Radiative Energy Transfer (RET) to radiowave propagation through vegetation at frequencies between 1 and 65 GHz as partner in a consortium including QinetiQ and Rutherford Appleton Laboratories. The outcome this work has resulted in an update of ITU-R P.833. Other projects included for instance optimising base station antenna design for mobile networks. For a number of years Jürgen Richter has also been involved in work on developing efficient propagation models for BFWA systems.
