The present invention is related to a system for transferring a beam of electromagnetic radiation having a vacuum wavelength. The system according to the invention includes a first dielectric medium, a second dielectric medium and a dielectric layer in between the first and the second medium. The dielectric layer has a periodicity of the dielectric properties parallel to the layer. The periodicity has a period that is smaller than the wavelength of the electromagnetic radiation in the second dielectric medium.
