Abstract

Metal nanoantenna arrays1,2 are typically designed and simulated using an ideal (smooth) geometry, and degraded experimental performance due to surface roughness, interior defects, and other effects are taken into account through a single value, a material 'loss factor'; although a 2-D roughness has been introduced in simulations for plasmonic metamagnetics3. Here, we aim to treat roughness independently from other types of loss by introducing a controlled roughened geometry into the FE model. The effect of various geometric defects on the resulting electromagnetic model, specifically, transmission and reflection spectra, will be presented.
