摘要：
A device capable to transmit images with sub-wavelength resolution is proposed in this paper. The structure is formed by an array of parallel conducting wires (wire medium) and effectively operates as a telegraph which captures a distribution of the electric field at the front interface and transmits it to the back side without distortions. This regime of operation is called canalization and is inherent in flat lenses formed by electromagnetic crystals. The theoretical estimations are supported by numerical simulations and experimental verification. The sub-wavelength resolution of lambda/15 and 18% bandwidth of operation are demonstrated at gigahertz frequencies. The structure is capable to transport sub-wavelength images without distortion to nearly unlimited distances.
