Key Points

To investigate the scattering behavior of surface plasmon polaritons interacting with a dielectric nanocube embedded in a metal layer across visible wavelengths.
Simulated surface plasmon polariton propagation and scattering at a planar metal-dielectric interface using finite element method-based modeling.
Calculated scattering and absorption cross sections, reflectance, transmittance, and far-field radiation patterns across the visible spectrum as a function of nanocube edge length.
Excitation of plasmonic eigenmodes within the embedded nanocube dictates the primary spectral features and efficiency of the scattering process.
Scattering into out-of-plane radiating modes peaks during the excitation of a dipolar-like plasmonic mode.
The resonance frequency of the radiating mode shifts predictably with modifications to the physical edge length of the nanocube.
