Abstract

This work reports on the extraordinary THz transmission properties of shape optimized metallic subwavelength aperture arrays, and its dependence upon incident beam angle. The resonant frequency of the aperture array has been shown to vary between 0.82 – 0.97 THz due to incident angle alone, while maintaining excellent (>85%) peak transmission.
