Electromagnetic metastructures stand for the artificial structures with a characteristic size
smaller than the wavelength, which may efficiently manipulate the states of light. However …

This paper reports an exhaustive review of recent research progress in the development of
millimeter-wave absorbers. With the advancement in technologies, microwave absorbers …

We report the simulation, fabrication, and experimental characterization of a multichannel
metamaterial absorber with the aim to be used as a label-free sensing platform in the …

The research investigates the sensing characteristics of the ultrathin metamaterial absorber
for refractive index detection of biomedical samples. The absorber is made up of a novel …

In this study, a novel multi‐band metamaterial absorber has been proposed which is ultra‐
thin, compact, polarisation‐insensitive and wide‐angle absorptive. The proposed structure …

Perfect absorbers are indispensable components for energy harvesting applications. While
many absorbers have been proposed, they encounter inevitable drawbacks including …

In this paper, a bandwidth-enhanced and wide-angle-of-incidence metamaterial absorber is
proposed using a hybrid unit cell. Owing to symmetric unit cells, high absorptivity is …

This manuscript proposes a polarization-insensitive multi-band metamaterial (MTM)
absorber for terahertz (THz) applications. The overall size of the proposed unit cell is 130× …

Since the initial demonstration of negative refraction and cloaking using metamaterials,
there has been enormous interest and progress in making practical devices based on …

In this work, we are proposing a silicon (Si) based concentric tube broadband absorber. The
proposed broadband absorber is composed of consecutive concentric tubes of intrinsic Si …
