The authors demonstrate a mechanism for focusing at optical frequencies based on the use of nanohole quasiperiodic arrays in metal screens. Using coherent illumination at and scanning aperture optical microscopy, “hot spots” were observed at a distance of from the array. Even smaller hot spots of about in waist were observed closer to the plane of the array.
