In one aspect, a surface plasmon based sensing device includes a substrate and a layer of an anti-reflective coating over the substrate. The surface Plasmon based sensing device includes a dielectric material on the anti-reflective coating shaped to form a 2-dimensional array of nanoholes spaced from one another. Also, the surface Plasmon based sensing device includes a layer of a metallic film formed on the 2-dimensional array of nanoholes to include openings over the nanoholes, respectively, wherein the sensing device is structured to support both propagating surface plasmon polariton (SPP) waves and localized surface plasmon resonant (LSPR) modes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensing devices and techniques using 3-D arrays based on surface plasmon excitations","description":"Techniques, apparatus, material and systems are described for implementing a three-dimensional composite mushroom-like metallodielectric nanostructure.
