Fig. 6From: A slanted-nanoaperture metal lens: subdiffraction-limited focusing of light in the intermediate field regionBeam focusing effects of an all-dielectric (Si/silica) slanted-nanoslit-array nanolens. a FDTD simulation of transmission pattern simulated at 633 nm wavelength. The same structure and dimensions are assumed as the Ag lens case (Fig. 3). b The intensity profile scanned at the focal planeBack to article page
