Orizzonte Sistemi Navali attended from 14 to 19 July the2024 IEEE International Symposium on Antennas and Propagation and ITNC-USNC-URSI Radio Science Meeting, at the "Fortezza da Basso"conference center in Florence. The event brought together leading researchers,engineers and professionals from around the world to share knowledge and expertise on the latest advances in antennas and propagation, radio science and electromagnetic engineering. From antenna design and analysis to electromagnetic theory, wireless communications systems and beyond, we explore the pioneering research and applications that are shaping the future of this dynamic field. The symposium was an opportunity to attend a wide range of talks, technical sessions and interactive workshops that covered a wide variety of topics in this specific and very important technological sector. For OSN itwas an opportunity to illustrate its expertise in the field of electromagnetic compatibility, in defining the topsides of Naval Units and more generally toshare the role of the Whole Warship and Combat System Design Authority company on military Naval Units.
