Exemplary embodiment can utilize the properties of tunable thin-film, material (eg,
graphene) to efficiently modulate the intensity, phase, and/or polarization of transmitted …

The next generation of infrared imaging systems requires control of fundamental
electromagnetic processes–absorption, polarization, spectral bandwidth–at the pixel level to …

The current focus in Swedish policy towards national security and high-end technical
systems, together with a rapid development in multispectral sensor technology, adds to the …

We examined the spectral responsivity of a 1.77 μm thick type-II superlattice based long-
wave infrared detector in combination with metallic nanoantennas. Coupling between the …

In this work, we proposed a low cost material to be used as an excellent absorber for solar
collectors, to increase its thermal efficiency by the high capacity to absorb solar radiation …

In this work, a broadband infrared metamaterial absorber is proposed based on trapezoid-
shaped anodic aluminum oxide (AAO) template. Unlike traditional metamaterial absorber …

Fourier modal expansion techniques are very well suited for electromagnetic (EM) scattering
in planar periodic stratified media. These techniques expand the transverse EM fields in …

Spoof surface modes on nanostructured metallic surfaces are known to have tailorable
dispersion dependent on the geometric characteristics of the periodic pattern. Here we …

We demonstrate the effects of integrating a nanoantenna to a midwave infrared (MWIR) focal
plane array (FPA). We model an antenna-coupled photodetector with a nanoantenna …
