We use the finite-element method to simulate light transmission through a 2D periodic array of rectangular apertures in a film of highly conductive material. We report results with a relative error of transmissivity lower than 0.01%. This is an improvement of about one order of magnitude compared to previously reported results. Further, the influence of corner and edge roundings on light transmission through the subwavelength apertures is investigated.
