Abstract

Is it possible to manipulate an electromagnetic field pattern on a much smaller scale than the wavelength of the incident radiation? The answer is, Yes! It turns out that the solution to such a problem does not go against the principles of optics that limit the size of a light spot to half the wavelength of the incident radiation. We explain how to achieve this, and provide examples to illustrate the concept. We also discuss the latest applications of this new technique and its future potential.
