Recent advances in communication and radar technologies are driving a paradigm shift in electromagnetic engineering, characterized by operation at millimeter-wave frequencies and beyond, hybrid active and quasi-optical beamforming architectures, smart reconfigurable surfaces, integrated sensing and communication, and innovative manufacturing techniques.

These emerging technologies demand advanced computational approaches for the accurate analysis, design, and optimization of complex electromagnetic structures. This focused session invites contributions on recent developments in computational electromagnetics, including, but not limited to, quasi-optical solvers, rigorous techniques for controlling the radiation of periodic structures, fast and accurate methods for large-scale problems, electromagnetic propagation through both artificial and natural complex media, and optimization strategies for antenna arrays and reconfigurable surfaces.
