The European Conference on Antennas and Propagation (EuCAP) 2023 will be held from March 26-31 in Florence, Italy. This flagship conference will offer convened sessions, short courses, and workshops, and provides a forum for the European R&D communities in the antennas and propagation field, at both academic as well as industrial levels. The event will focus on various topics, among others, that include mm-wave antennas, antenna systems, and architecture, antenna coupling, and manufacturing, electromagnetic theory (EMT), applications of machine learning in EMT, electromagnetic education, propagation theory, empirical and statistical modeling of channels, machine learning for propagation, and measurement topics. It is a great forum for exchanging new technical-scientific achievements, demonstrating state-of-the-art technology, and establishing and strengthening professional networks.
