Here we realize a broadband absorber by using a hyperbolic metamaterial composed of alternating aluminum-alumina thin films based on superposition of multiple slow-wave modes. Our super absorber ensures broadband and polarization-insensitive light absorption over almost the entire solar spectrum, near-infrared and short-wavelength infrared regime (500–2500 nm) with a simulated absorption of ove...

This article presents the design, simulation and testing of an Ultra Wide Band (UWB) planar monopole antenna with WLAN band-notch characteristic. The proposed antenna consists, the combination of planar monopole antenna with partial ground and a pair of AMC structures. The AMC structure used for the design is mushroom-like. Design equation of EBG parameters is also proposed for FR4 substrate us...

Ultra-Wideband (UWB) technology has been gaining increasing interest from the industry due to its recent application in communications. The technology itself has been well known for decades and its use was mostly reduced to radars in industrial applications. During the standardization process which is not over yet, two realizations were proposed – Impulse Radio (IR), which has been known for ye...

Based on the effective medium theory for multilayers, we present the design of several all-angle, polarization-insensitive absorbers spanning the visible, near-IR and part of the mid-IR (from 400nm to 3500nm) using periodic, one-dimensional, metallo-dielectric structures. OCIS codes (310.4165) Multilayer design; (310.3915) Metallic, opaque, and absorbing coatings. Visible and IR absorbing mater...
