    Metamaterial Absorber: A Review
    (2023) Shaik Abdul Khadar; K.S.R. Sastry
    Due to their compact dimensions, minimal profile, and straightforward manufacturability, Metamaterial Absorbers have largely taken the place of conventional absorbers. These sub-wavelength unit cells, constituting the metamaterial, have been engineered to serve various purposes, encompassing tasks such as diminishing radar cross-section (RCS), displaying insensitivity to polarization, functioning as gas sensors, and enabling cloaking effects, among other applications. This comprehensive review encompasses an exploration of multiple applications for metamaterial absorbers. Several factors, including the dielectric constant's magnitude, the configuration involving resonant patches in a hybrid arrangement, and the gap between the dielectric substrate and metallic ground, collectively influence absorptive qualities, bandwidth, and the count of resonant bands.
