Metamaterial and Metasurface Antennas by Dr. Dibin George (UPRM) (Sept./18/25)
Abstract:
Metamaterials and metasurfaces have revolutionized electromagnetic engineering by facilitating
exceptional control over wave propagation, radiation, and scattering. In contrast to traditional
materials, these intentionally designed structures obtain their characteristics from geometry
rather than composition, facilitating advanced functions such as phase equalization, wavefront
manipulation, and downsizing. This presentation emphasizes innovative breakthroughs in
metamaterial and metasurface antennas, underscoring their promise in next-generation wireless
communication systems. The session includes theory, simulation, prototyping, and measurement
insights to furnish both foundational knowledge and practical viewpoints. This discussion will
encompass a series of antenna advancements, specifically substrate-integrated waveguide (SIW)
antennas with epsilon-near-zero (ENZ) material configurations, and ultra-wideband metasurface
antennas for millimeter-wave applications. ENZ materials are utilized to provide a typical
electromagnetic tunneling via ultra-thin subwavelength channels, hence permitting highly
directional narrowband antenna designs. Metamaterial and metasurface antennas exhibit
enhanced directivity, scalability, and functional diversity relative to traditional antenna designs,
facilitating their extensive implementation in novel wireless applications.
