Abstract:
An original realization of a lens capable of transmitting images with subwavelength resolution is proposed. The lens is formed by an array of parallel conducting wires and effectively operates as a telegraph which captures a distribution of the electric field at the front interface of the lens 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 subwavelength resolution of /15 and 18% bandwidth of operation are demonstrated at gigahertz frequencies. The proposed lens is capable of transporting subwavelength images without distortion to nearly unlimited distances since the influence of losses to the lens operation is negligibly small.
