Terahertz (THz) technology has attracted great worldwide interest and novel high-intensity
THz sources and plasmonics are two of the most active fields of recent research. Being …

In the past two decades, the development and steady improvement of terahertz technology
has motivated a wide range of scientific studies designed to discover and develop terahertz …

The advent of negative index materials has spawned extensive research into metamaterials
over the past decade. Metamaterials are attractive not only for their exotic electromagnetic …

In this Letter we demonstrate, for the first time, selective thermal emitters based on
metamaterial perfect absorbers. We experimentally realize a narrow band midinfrared (MIR) …

Graphene can be utilized in designing tunable terahertz devices due to its tunability of sheet
conductivity. In this paper, we combine the metamaterial having unit cell of cross-shaped …

Photonic crystal slabs (PCSs) are a well-studied class of devices known to support optical
Fano resonances for light normally incident to the slab, useful for narrow-band filters …

We demonstrate, for the first time, a spatially dependent metamaterial perfect absorber
operating in the infrared regime. We achieve an experimental absorption of 97% at a …

Metamaterial-based perfect absorbers utilize intrinsic loss, with the aid of appropriate
structural design, to achieve near unity absorption at a certain wavelength. For most of the …

By relying on an advanced Jones calculus, we analyze the polarization properties of light
upon propagation through metamaterial slabs in a comprehensive manner. Based on …

We present the theory, design, and realization of a polarization-insensitive metamaterial
absorber for terahertz frequencies. Effective-medium theory is used to describe the …
