Abstract: Subwavelength nanoantennas supporting multipole resonances provide a versatile platform for controlling light–matter interaction at the nanoscale. By engineering nanoantenna geometry, size, and material composition, tailored electric and magnetic multipolar responses are realized across the visible and near-infrared spectral regions, enabling strong electromagnetic field confinement. Low-loss, high-refractive-index nanostructures are employed to access and tune the interference between multiple resonant channels, yielding highly directional scattering characteristics. A particular emphasis is placed on the coupling of quantum emitters to multipolar resonant nanoantennas, where the engineered modal landscape governs emission rates, radiation directivity, and coupling efficiency. The role of refractive-index contrast in activating and controlling specific multipole interactions is analyzed, revealing pathways to manipulate both classical scattering and quantum emission. These results position multipolar nanoantennas as key building blocks for quantum nanophotonics, with implications for nanoscale light sources, sensing, and integrated quantum optical systems.
