Abstract

This tool allows users to perform FDTD (finite difference time domain) simulations of bowtie antennae of arbitrary geometry. The heart of the simulation is open source MEEP package. Material properties (ex. gold, silver) are fully implemented across the entire optical range. The radiation source, antenna environment, and outputs are user-specified. Outputs include: (1) simulation log; (2) sequences of planar png images (with dynamically scaled colorbar) in time; (3) sequences of volume slice "heightmap" plots in time; (4) sequences of volume cartesian slices in time; (5) dynamic calculation of points of maximum enhancement or electric field energy density; (6) field component energy densities plotted versus time at a specified point (in conjunction with (5)); (7) field component energy densities plotted versus wavelength at a specified point (in conjunction with (5)); (8) field component energy densities plotted versus frequency at a specified point (in conjunction with (5)); (9) overlay plot of "bare source" fields for (6-8) Note that this tool can be used to identify resonances for various antenna geometries. A useful strategy is to radiate the antenna with a gaussian source (in the optical regime, an 800nm wavelength source with temporal width 2 femtosec. and duration of 30 temporal widths is appropriate) and look for the spectral peak. Coming soon in version 2.0: 1) Placement of multiple bowtie antennae in arbitrary arrangements 2) Placement of simulated spherical AFM tip 3) New material models 4) Parallel computing support
