- 요약Shaping and controlling the distribution of electromagnetic waves has wide-ranging scientific and practical implications. In this dissertation, I investigate two themes in photonics: the design and functionality of non-local metasurfaces and the topological structures in electromagnetic waves.Non-local metasurfaces offer highly versatile responses. By engineering their guided resonances, transmission zeros, or by employing computational optimization, their transmission properties can be precisely controlled. Leveraging these capabilities, I demonstrate their potential for performing optical differentiation under incoherent light, generating spatiotemporal optical vortices, and enabling compact implementations of general optical convolution. These results highlight potential opportunities toward the development of compact and multifunctional photonic devices.Electromagnetic waves in free space also host a rich set of topological structures. In this dissertation, I show that configurations such as skyrmions, hopfions, and Shankar skyrmions can all be realized in free-space optical waves. Homotopy theory provides a rigorous classification of these textures and guides the search for new topological configurations in optical fields. These findings open future directions in studying light-matter interactions involving topological structures and motivate the investigation of analogous phenomena in other physical systems, such as mechanical or quantum waves.
