ABSTRACT
We employ numerical simulations to show that highly localized, enhanced electromagnetic fields, also known as “hot spots,” produced by a periodic array of silver nanoantennas can be spatially translated to the other side of a metal-dielectric composite superlens. The proposed translation of the hot spots enables surface-enhanced optical spectroscopy without the undesirable contact of molecules with metal, and thus it broadens and reinforces the potential applications of sensing based on field-enhanced fluorescence and surface-enhanced Raman scattering.

    The force fields, in-plane vibrations, and relative intensities of Raman spectra have been calculated and analyzed for the N1H and N3H tautomers of imidazole, imidazolium cation, and their model structures. The results obtained for the isolated state of imidazole correspond to the intramolecular...
