Metamaterials are engineered composite materials offering unprecedented control of wave
propagation. Despite their complexity, effective properties can frequently be extracted by …

Recently perfect metamaterial absorbers triggered some fascination since they permit the
observation of an extreme interaction of light with a nanostructured thin film. For the first time …

In this paper, we review the invisibility cloak design methodologies and their experimental
developments from a practical perspective, as well as basic underlying theories, derived …

Electromagnetic metamaterials are artificial materials composed of subwavelength
structures to provide unusual effective macroscopic behavior not found in nature. These …

Metamaterial concepts have opened the door to high-optical anisotropy beyond levels of
naturally occurring materials but usually with limited spectral bandwidth. Here, we report on …

Previous cylindrical hyperlenses were realized with metamaterial with only one component
of the constitutive parameters negative. In this letter, we show that metamaterials with …

An equivalent circuit model of 'U'-shaped split-ring resonators (SRR), the basic structure of
SRR has been proposed and studied. The proposed model, other than traditional equivalent …

The availability of novel technologies that enable the fabrication of bulk metamaterials made
it necessary to develop a theoretical language to discuss their properties appropriately. Here …

THz (Terahertz) radiation sources are an important research topic in THz science and
technology. Novel THz radiation using double negative metamaterials (DNMs) and electron …

In this paper, we present the first experimental demonstration of double-and triple-band
negative refraction index meta-foils in the terahertz (THz) region. Multi-band meta-foils …
