Abstract:

The engineering of multipole resonances in subwavelength nanoantennas is explored for adaptive nanophotonic functionalities across the visible and near-infrared spectral regions. By tailoring nanoantenna geometry, dimensions, and material composition, complex resonant responses are induced, enabling strong confinement and precise manipulation of electromagnetic fields at subwavelength scales. Nanoantennas based on low-loss, high-refractive-index materials, are designed to support both electric and magnetic multipole resonances. The tunability of these resonances allows controlled interference between different multipolar modes, leading to pronounced directional scattering responses. In addition to classical scattering control, the interaction of quantum emitters with multipolar-resonant nanoantennas is analyzed, demonstrating modified emission rates, radiation patterns, and coupling efficiencies governed by the engineered multipole landscape. By introducing strong refractive-index contrasts, tailored excitation and interplay of multipole modes are achieved, resulting in unidirectional scattering and controlled quantum emission relevant to sensing, imaging, communication, and quantum nanophotonic applications.
