Efficient absorption of solar radiation is desired for the renewable energy sector, such as
solar thermophotovoltaics and solar thermal applications. In order to minimize thermal re …

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 …

Perfect optical metamaterial absorbers (POMMA) utilize intrinsic loss, with the aid of
appropriate structural design, to achieve near unity absorption at a certain wavelength. In all …

Incandescent filaments and membranes are often used as infrared sources despite their low
efficiency, broad angular emission, and lack of spectral selectivity. Here, we introduce a …

Future Internet of Things (IoT) devices are expected to be fully ubiquitous. To achieve this
vision, a new generation of IoT devices needs to be developed, which can operate …

In this paper, the design, simulation, fabrication, and measurement of an ultrathin and
broadband microwave metamaterial absorber (MMA) based on a double-layer structure are …

This paper proposes a metamaterial absorber design for solar energy harvesting using a
simplified and symmetric structure. A unit cell of this design consists of three important layers …

A simple 2D SiC grating based surface Plasmon resonance (SPR) gas sensor operating in
thermal infrared wavelengths is proposed for refractive index sensing. The performance of …

An infrared dual-band perfect absorber based on asymmetric T-shaped plasmonic array is
designed and numerically investigated. Two distinct absorption peaks are achieved by …

In this paper, we propose and demonstrate a dual-band metamaterial absorber at normal
incidence based on a five-layer metal-insulator-metal (MIM) stacked structure. The designed …
