Abstract

In the paper metamaterial nanotips with multi-frequency local field enhancement are proposed and studied theoretically and numerically. The nanotips are in form of pyramids built from silver nanoplates embedded in a dielectric block. The pyramids are layered structures with subsequent plates parallel to the pyramid base. Thickness of nanoplates and their transversal size is chosen to efficiently convert the light impinging on the pyramid base into hot spots near the pyramid apex, and also to support large number of plasmonic resonances which allow for multi-frequency enhancement of the light intensity. Geometrical parameters are designed to cover the visible light range.
