We present the analysis and first results from the Reflection Grating Spectrometer (RGS) during the 320 ks XMM-Newton observation of the Seyfert 1 galaxy MCG–6-30-15. The spectrum is marked by a sharp drop in flux at 0.7 keV which has been interpreted by Branduardi-Raymont et al. using RGS spectra from an earlier and shorter observation as the blue wing of a strong relativistic OVIII emission l...

Artificial electromagnetic metamaterial produces exotic resonance, unusual characteristics not found in nature, but engineers can inherit the by controlling and manipulating their architecture. The design realization of dual-band, polarization, incident angle insensitive absorber (MA) is proposed. By shape structure, periodic pattern, dielectric layer thickness a significant way to realize high...

In this study authors worked to attain a metamaterial absorber for visible and infrared region using bismuth as its main constituent material. Proposed would be used various applications; solar cell, communication etc. To model the surface, two different sets of materials are observe compare absorption, having metal-insulator-metal structure metamaterial. It is observed that proposed layer Al/T...

Abstract Reconfigurable metasurface absorbers enable collecting or emitting radiation within selected frequency bands. It is thus necessary to decipher such behavior for many applications, including plasmonic energy harvesting, radiative cooling and thermal emitters. In this article, we propose a compact reconfigurable vanadium dioxide (VO 2 )-based absorber/emitter demonstrate switching betwee...
