Field confinement and distribution in isolated SRR structures.
Schematic diagrams of planar (a) and vertical SRR (c) of identicaldimensions. Parameter L indicates the length of base rod (L =195 nm). The induced magnetic energy density in arbitrary unitunder normal incidence at plasmon resonance is shown in two perpendicularplanes for comparison. Observation planes are shown as insets in (b) and(d). The side views (left) in (b) and (d) are for the plane that is centeredalong the SRR bas rods, the top views (right) in (b) and (d) are for theplane inserted between the base rod and the two prongs. Arrows in magentaindicate the direction of the induced surface current.
