Original realization of a lens capable to transmit images with sub-wavelengthresolution is proposed. The lens is formed by parallel conducting wires andeffectively operates as a telegraph: it captures image at the front interfaceand the transmit it to the back interface without distortion. This regime ofoperation is called canalization and is inherent in flat lenses formed byelectromagnetic crystals. The theoretical estimations are supported bynumerical simulations and experimental verification. Sub-wavelength resolutionof $\lambda/15$ and 18% bandwidth of operation are demonstrated at gigahertzfrequencies. The proposed lens is capable to transport sub-wavelength imageswithout distortion to nearly unlimited distances since the influence of lossesto the lens operation is negligibly small.Comment: 4 pages, 4 figures, submitted to PR
