Abstract :
The paper discusses how at optical frequencies conducting sheets can be used for amplification of the evanescent waves and how these can be used to see beyond the diffraction limit. It extends Caesar Monzon´s [6] work and shows, how multiple loop antennas of different radii and placed above the resistive surface can be efficiently resolved.
