Investigating the Broadband Microwave Absorption of Nanodiamond Impurities [PDF]
Broadband microwave complex permittivity measurements of nanodiamond powders are presented. Previous studies show that measurements of dielectric loss strongly correlate with the presence of nondiamond surface impurities. In this study, the frequency dependence of these losses is investigated using the microwave cavity perturbation (MCP) and broadband ...

Ultra-Broadband Infrared Absorbers Using Iron Thin Layers
We theoretically proposed an ultra-broadband infrared light absorber and demonstrated that a high absorption could be obtained in the range of ultra-broadband infrared light using the iron thin layers.

Resonance absorption of a broadband laser pulse [PDF]
Broad bandwidth, infrared light sources have the potential to revolutionize inertial confinement fusion (ICF) by suppressing laser-plasma instabilities. There is, however, a tradeoff: The broad bandwidth precludes high efficiency conversion from the infrared to the ultraviolet, where laser-plasma interactions are weaker. Operation in the infrared could

Plasmonic absorbers for multispectral and broadband absorption [PDF]
We present polarization dependent multispectral and broadband plasmonic absorbers in the visible spectrum. The spectral characteristics of these structures are tunable over a broad spectrum. Experimental results are verified with the FDTD and RCWA analysis methods.

Recoverable Broadband Absorption Based on Ultra-Flexible Meta-Surfaces
In this work, we demonstrated a tunable metamaterial perfect absorber (MPA) with broadband absorption by tuning the different states of flexible sandwiched structures (graphene conductive ink/rubber/metallic layers). The broadband absorption spectrum was

Broadband terahertz metamaterial absorber with two interlaced fishnet layers
The realization of broadband absorption in the terahertz regime is of significant interest in high-sensitive signal detection and modulation. Previously, multi-layer metamaterials have been proposed and demonstrated to expand the absorption bandwidth by ...
