Bio

Rafael F. S. Caldeirinha (Fellow Member IET and Senior Member IEEE) was born in Leiria, Portugal, in 1974. He received the BEng (Hons) degree in Electronic and Communication Engineering from the University of Glamorgan, UK, in 1997. In 2001, he was awarded a Ph.D in Radiowave Propagation by the same University for his research work in vegetation studies at frequencies from 1 to 62.4 GHz. He is currently Head of the Antennas & Propagation (A&P-Lr) research group at Instituto de Telecomunicações, Leiria, Portugal, and Coordinator Professor in Mobile Communications at the School of Technology and Management (ESTG) of the Polytechnic Institute of Leiria (IPLeiria), Portugal.

His research interests include studies of radiowave propagation through vegetation media, radio channel sounding and modeling and frequency selective surfaces, for applications at microwave and millimetre wave frequencies.

Prof. Caldeirinha has authored or co-authored more than 200 papers in conferences and international journals and 4 contributions to ITU-R Study Group, which formed the basis of the ITU-R P.833-5 (2005) recommendation. He is Associate Editor of the IEEE Transactions on Antennas and Propagation journal; Associate Editor of the IET on Microwaves, Antennas and Propagation journal; Member of the editorial board of the International Journal of Communication Systems, IJCS (New York, Wiley); Program chair of WINSYS International Conference between 2006 and 2012; Appointed Officer for Awards and Recognitions of the IEEE Portugal section in 2014; Chair of the IEEE Portugal Joint Chapter on Antennas & Propagation - Electron Devices - Microwave Theory & Techniques since 2016; Regional Delegate of European Association for Antennas and Propagation (EurAAP) for Andorra, Portugal and Spain since March, 2017; Chair of the Scientific Committee F (Propagation and Remote Sensing) of the Portuguese International Union of Radio Science (URSI) Committee; and a Senior Member of URSI, Senior Member of IEEE and Fellow Member of IET.
