This engineering study investigates a plasmonic nanostructure composed of a spherical metallic nanoshell with a small metallic nanoparticle (“nanoknob”) on its surface. It reports tunable plasmon resonance behavior driven by nanoshell properties and localized/enhanced electromagnetic fields near the nanoknob under…
