The array of pointed-shape apertures microfabricated in thin-film aluminum on a thick silicon substrate was designed to maximize the transmission efficiency at desired frequency. The resulted characteristics were over 100% optical transmission (relative to substrate) at narrow band-pass resonance and polarization-independent transmission strength and band-pass shape on filter rotation angle.
