Further, Metasurface (MS)-enabled electromagnetic technologies are emerging as
powerful
enablers for the development of next-generation radar and sensing systems, offering
unprecedented capabilities for wavefront engineering, dynamic beam control,
polarization
manipulation, aperture reconfiguration, and multifunctional operation. In
particular,
MS-enabled reflectarrays (RAs), transmitarrays (TAs), transmit–reflectarrays (TRAs),
reconfigurable intelligent surfaces (RISs), and adaptive electromagnetic apertures
provide attractive alternatives to conventional phased-array architectures by
enabling
low-profile, lightweight, cost-effective, and highly efficient radar front ends.
This
special session also aims to bring together researchers, engineers, and
practitioners
from academia, industry, government laboratories, and research organizations to
present
and discuss recent advances in metasurface-based antennas and intelligent
electromagnetic surfaces for radar, sensing, imaging, and integrated sensing and
communication (ISAC). The session will cover theoretical developments,
electromagnetic
design methodologies, fabrication and measurement techniques, system-level
demonstrations, and emerging applications. Particular emphasis will be placed on
dynamic
and reconfigurable metasurfaces, intelligent surfaces, beam steering and beam
shaping,
OAM-based radar, multifunctional and multibeam apertures, MIMO radar, mmWave/THz
sensing, radar imaging, and adaptive electromagnetic systems.
