Active Two-Dimensional Steering of Radiation from a Nanoaperture
[Image: see text] We experimentally demonstrate control over the direction of radiation of a beam that passes through a square nanoaperture in a metal film. The ratio of the aperture size and the wavelength is such that only three guided modes, each with different spatial symmetries, can be excited....
