Biography

Alessandro Garufo received the M.Sc. degree in telecommunication engineering from the University of Siena, Siena, Italy, in 2012 and the Ph.D. degree from Delft Universit of Technology, Delft, in 2017.

From March 2011 to February 2012, he was as an intern in the Antenna Group at Thales Alenia Space, Rome, Italy, where he developed his Master degree thesis. From April 2012 until September 2012, he was a researcher in the Applied Electromagnetic Laboratory (LEA) at the University of Siena, Siena, Italy. From November 2013 until April 2014 he was a visiting scholar in the Metamaterials and Plasmonics Research Laboratory University of Texas at Austin, Austin, Texas, USA. Currently he is a postdoc in the THz Sensing Group of EEMCS department of Delft University of Technology, Delft, The Netherland

His research interest includes analytical and numerical method for antennas and transmission lines characterization, modelling and design of THz sources based on photoconductor and design of antennas, dielectric lens antennas and antenna arrays.
