Recently it has been shown that plasmonic effects in hyperbolic metamaterials may facilitate overcoming the diffraction limit and enhance the contrast function of an image by filtering background radiation. Unfortunately, the contrast function of such a dark‐field hyperlens degrades in the deep‐subwavelength regime. We push forward the concept of the contrast function revival in the subwavelength...
All-dielectric metamaterials are the growing trend in optics and electromagnetics. They require materials with high permittivity, for example silicon in photonics. Aiming the microwaves range we present here water as a unique substance for employing in metamaterials design. Dependence of water parameters on temperature and easy reconfiguring of the shape of unit elements make water metamaterials promising...
Plasmonics for the mid-infrared wavelength regime offers unique applications such as molecular vibrational absorption spectroscopy for bio-sensing [1]. The quest for novel materials and structures has been continuing in the last decade [2]. Meanwhile, the fabrication of plasmonic metamaterial structures with large area in a reproducible manner is a tremendous challenge. In this report we show that...
In this paper we analyze surface electromagnetic waves supported at an interface between an isotropic medium and an effective anisotropic material that can be realized by alternating conductive and dielectric layers with deep subwavelength thicknesses. This configuration can host various types of surface waves and, therefore, can serve as a platform allowing many applications for surface photonics...
Using a metamaterial composite, we demonstrate a bandpass filter that has only a single transmission mode from 0 to >25 THz. This usable bandwidth matches, or exceeds, that of currently used THz sources.
