Abstract:Antenna-based near-field optical microscopy and spectroscopy makes use of locally enhanced optical fields created near laser-irradiated metal nanostructures acting as local probes. Using three-dimensional simulations based on the finite element method we study the electromagnetic fields near various optical antennas and we optimize their geometry in order to bring out a strong enhancement in a selected frequency range. Our results provide clear guidelines for the fabrication of efficient antenna structures and for improving the sensitivity of current near-field microscopy schemes.
