Article Synopsis
- Scientists are studying special patterns called quasicrystalline lattices made of tiny gold balls (nanoparticles).
- They used a new method to create these tiny balls and a theory to understand how they scatter light.
- Their results show that these unique patterns can create special light effects that regular patterns can't, and their findings match well with real experiments.
The optical properties of a dimer type nanoantenna loaded with a plasmonic nanoring are investigated through numerical simulations and measurements of fabricated prototypes. It is demonstrated that by judiciously choosing the nanoring geometry it is possible to engineer its electromagnetic properties and thus devise an effective wavelength dependent nanoswitch. The latter provides a mechanism for controlling the coupling between the dimer particles, and in particular to establish a pair of coupled/de-coupled states for the total structure, that effectively results in its dual mode response.
