Abstract

Here I report on comparisons between two different techniques in fabricating arrays of subwavelength cross-shaped apertures in metallic screens. The aim was to determine the most appropriate fabrication technique to be used considering the cost, ease of fabrication and accuracy in which the apertures were created. Some interesting physical effects are observed.
