Dear {{lead.First Name:default=edit me}},

As we welcome 2025, I’m excited to share the first issue of IEEE Transactions on Antennas and Propagation and reflect on our 2024 milestones, as well as our aspirations for the year ahead, in my editorial message.

Explore the 24 most-read articles published in 2024 along with an invited article about New and Emerging Directions in the Fields of Antennas and Propagation, now available as open access through February 2025. Also, contribute to our new Special Issues on: Microwave, mm and THz Imaging and Sensing Systems and Technologies for Medical Applications and Numerical and Analytical Methods for Complex Electromagnetic Media.

We greatly value your engagement and your vital role in driving innovation, exploring new frontiers, and enhancing the reach and impact of our journal. Thank you for being an integral part of our vibrant community.

With gratitude and best wishes,

Konstantina S. Nikita
