Gold “nanograils”, novel plasmonic nanostructures that can be represented as three different‐sized rings connected vertically by curved surfaces, similar to a miniaturized grail, are presented. Reflectance measurements and FDTD simulations demonstrate the existence of strong multiple plasmon resonances with the same dipolar symmetry around the sharp ring edges of the nanograils.
