Alessandro Calcaterra was born in Rome, Italy, on January 21st in 1993. He received the Bachelor and the Master degree in Electronic Engineering with full marks and honors, both from the University of Rome "La Sapienza" in 2014 and 2017 respectively. During his academic path he attended two different advanced courses, in which he could deeply improve his knowledge in electromagnetic theory, in the materials' characterization at microwave frequencies and in the leaky-wave antennas. In particular, the latter represents his main topic of interest that he could enhance by attending the ESOA course on "Leaky-waves and periodic structures for antenna applications" in 2017. At the moment, he is studying the deep penetration phenomenon and how to achieve it using inhomogeneous waves such as leaky ones.
