Figure 7

FDTD simulations showing the electric field distribution for only medium NPs at (a) λ=390 nm and (b) λ=650 nm, and for medium and small NPs at (c) λ=390 nm and (d) λ=650 nm. (e) Snapshot from the time-domain simulation for medium and small NPs. All NPs are embedded into the surface by half of their radius.
