Abstract

We use a nanofabricated gold grating to validate two-dimensional spatial harmonic analysis (2D SHA) method, also known as Fourier modal method or rigorous coupled-wave analysis under oblique incidence. The transmittance spectra of the metal grating for incident angles of 0°-30° are obtained in both experiments and simulations at the zero diffraction order. The simulations are performed with our custom software, a fully functional web-based 2D SHA tool, which has been staged at nanoHUB.org and is free to use. The simulation results are compared to experimentally measured values, and a good fit is achieved for all incident angles. Possible reasons for experiment-simulation mismatch in actual nano-plasmonic structures are also discussed.
