A dual layer broadband radar absorber to minimize electromagnetic interference in radomes

Single-Layer Metamaterial Absorber for Radar Application

Metasurface Broadband Solar Absorber

We demonstrate a broadband, polarization independent, wide-angle absorber based on a metallic metasurface architecture, which accomplishes greater than 90% absorptance in the visible and near-infrared range of the solar spectrum, and exhibits low absorptivity (emissivity) at mid- and far-infrared wavelengths. The complex unit cell of the metasurface solar absorber consists of eight pairs of gol...

A broadband low-reflection metamaterial absorber

Artificially engineered metamaterials have enabled the creation of electromagnetic materials with properties not found in nature. Recent work has demonstrated the feasibility of developing high performance, narrowband electromagnetic absorbers using such metamaterials. These metamaterials derive their absorption properties primarily through dielectric loss and impedance matching at resonance. T...

Review Paper on Microwave Absorber Using FSS

Microwave absorber are used in Military application, EMI reduction, Antenna pattern shaping, Radar cross reduction. Frequencyselective surfaces have been most commonly used in the radio frequency region of the electromagnetic spectrum and find use in applications as diverse as the aforementioned microwave oven, antenna radomes and modern metamaterials. One of the most important applic ations of...

Electromagnetic Absorber Realization Using Huygens Metasurfaces

In this paper, the possible realization of the electromagnetic (EM) absorber as a thin metasurface is considered. The metasurface is based on establishing a passive surface of electric and magnetic currents using the Huygen’s principle. So, the absorber is named Huygens Absorber (HA). The metasurface can be designed using split meander lines with spiral rings. In this way, both sides of the sub...
