Composite wire metamaterial for broadband infrared superlensing — •Mike Prämassing, Tobias Maß, and Thomas Taubner — I. Institute of Physics, RWTH Aachen University

Superlenses can either consist of natural [1] or metamaterials and enable subwavelength imaging beyond Abbes diffraction limit. Thereby, the evanescent near-fields are preserved and subwavelength information is transported [2]. We investigate a composite wire metamaterial consisting of parallel aligned metallic nanowires in a dielectric host medium. Its superlensing effect originates from strongly anisotropic optical properties [3,4]. Our theoretical investigations of the imaging properties concern the mid-infrared spectral range from 1 - 10µm. Furthermore we provide first fabrication attempts by means of electrochemical deposition [5].
