Technique for measuring the spatial field distribution in tapered wire medium

Abstract

The paper is devoted to experimental investigation of the spatial distribution of electromagnetic field in the vicinity of the tapered wire medium formed by copper wires conductors in the millimeter waveband. The technique of small perturbations was applied to analyze the spatial distribution of the field intensity in cross-section of the wire medium. The optimal type of probe has been found. The energy concentration in the vicinity of the narrow planes of the tapered wire medium has been demonstrated experimentally.
