A lot of recent interest has been focused on a new class of materials, the so‐called left‐
handed materials (LHMs) or negative‐index materials, which exhibit highly unusual …

The main directions of studies of materials with negative index of refraction, also called left-
handed or metamaterials, are reviewed. First, the physics of the phenomenon of negative …

Recently, there has been growing interest in the use of metamaterial (MTM)-based lenses,
also known as metalenses, as innovative antenna technology. Increasingly widespread …

In this paper, a novel design for a metamaterial lens (superlens) based on a Photonic
Crystal (PC) operating at visible wavelengths is reported. The proposed superlens consist of …

The anomalous diffraction effects arising in the intrinsically isotropic photonic crystal gratings
with different periods of the front-side and back-side interfaces are studied with the …

Metamaterial structures designed to have simultaneously negative permittivity and
permeability are known as left-handed materials. Their complexity and our understanding of …

Intensive research on fullerenes, nanoparticles, and quantum dots in the 1990s led to
interest in nanotubes and nanowires in subsequent years. Handbook of Nanophysics …

We perform an experimental study of the phase and amplitude of microwaves interacting
with and scattered by two-dimensional negative index metamaterials. The measurements …

In this paper we report directivity enhancement by a short-focal-length plano-concave lens
engineered by stacked subwavelength hole arrays (fishnet-like stack) with an effective …
