Multispectral Cesaro-Type Fractal Plasmonic Nanoantennas

Fractal-shaped nanoantennas have a large potential to enable multiband devices for surface-enhanced spectroscopy due to their scale-invariant geometry that gives rise to strongly enhanced local fields across different spectral ranges with multiscale spatial distributions. In particular, fractal nanoantennas based on plasmonic metals are promising for biodetection applications that extend from the near-infrared across the mid-infrared spectrum. In this context, we introduce novel multiscale resonant structures based on the inverse Cesaro space-filling fractal curve with the remarkable property that the number of resonant bands does not depend on the overall size of the structures. We systematically study their scattering and near-field resonant properties by resorting to full-field finite difference time domain simulations in combination with experimental Fourier transform infrared microspectroscopy. In particular, by investigating a number of gold antennas fabricated by electron-beam lithography on CaF2 s...
