Message From the Editor-in-Chief.

This June issue contains two sets of articles: the Special Issue on Artificial Intelligence in Radio Propagation for Communications and Regular Papers. This Special Issue is motivated by the fact that in recent years it has become evident that artificial intelligence provides new innovative solutions for complex problems. Therefore, the Editorial Board of the IEEE Transactions on Antennas and Propagation invited applications for special issues related to how artificial intelligence, machine learning, and deep learning can assist with challenges in the field of antennas and propagation. Three special issues were accepted and this one focuses on a unified vision for the application of artificial intelligence in the propagation of electromagnetic waves for applications related to communications.
