In this paper, we propose a tunable coordinated multi-band absorber that combines graphene with metal–dielectric–metal structures for the realization of multiple toward perfect absorption. The parametric inversion method is used to extract the eq

We present a hybrid Tamm system targeting the tunable multichannel absorber. The proposed optical absorber is analyzed and investigated by using the transfer matrix method (TMM). The numerical and theoretical studies show that the four perfect absorp

We use Hypergeometric Gaussian-II (HyGG-II) modes to investigate the impacts of non-Kolmogorov atmospheric turbulence on the Holevo channel capacity of a quantum communication scheme. The capacity of HyGG-II modes can be higher than that of Laguerre
Fano resonance is based on plasmonic metasurfaces and has many applications in all kinds of fields. In this paper, we propose an independently switchable double-layer raster structure based on graphene. Depending on the highly adjustable nature of gr

Graphene-based hyperbolic metamaterials are well known for their optical anisotropy, high absorption of electromagnetic radiation, and low energy loss. We proposed a novel multilayer graphene-silica hyperbolic metamaterial designed as a grating struc

It has been predicted theoretically, confirmed experimentally and using model validation that for a metamaterial consisting of electrically conducting rectangular omega resonators on a dielectric substrate, it is possible to convert an incident linea

In this work, we investigate the possibilities of reaching wide-angle perfect absorption with Huygens' metasurfaces possessing both electric and magnetic responses. We analyze the role of the anisotropy of the polarizability tensor of the unit cell a
We present a tunable multichannel absorbers in a hybird optical Tamm system at near-infrared frequencies. The simulation results reveal the structure capable of exciting four perfect absorption peaks, which are generated by two types of resonance, na
