| Formatted contents note | Metasurfaces, engineered with subwavelength structures, have transformed electromagnetic<br/>wave manipulation by offering unprecedented control over polarization, phase,<br/>and amplitude, enabling compact and efficient structures for modern wireless communication<br/>systems. However, existing designs suffer from narrow bandwidth, limited<br/>functionality, and fabrication complexity. This thesis presents novel multi-band reflective<br/>metasurfaces for efficient linear and circular polarization conversion, addressing<br/>these challenges. The proposed metasurfaces are designed using a unit cell approach,<br/>optimized through full-wave electromagnetic simulations, and verified experimentally<br/>in the X, Ku, K, Ka and U bands. The structures incorporates asymmetric resonators<br/>to achieve wideband operation with high efficiency. Results demonstrate an average<br/>polarization conversion efficiency exceeding 90% at oblique incidence angles up to 45°<br/>across the targeted bands, outperforming state-of-the-art designs. The metasurface<br/>achieves wideband operation while maintaining compactness. Experimental validation<br/>confirms excellent agreement with simulation results. The work complements prior<br/>advancements in polarization conversion, which can be extended to active wave manipulation<br/>through reconfigurable reflective metasurfaces, paving the way for innovative<br/>approaches in adaptive beamforming and dynamic polarization control. Overall, this<br/>work advances the field of metasurfaces, with potential applications in satellite communications,<br/>radar, and next-generation wireless networks. |
