Due to bulkyĪnd hard to realization nature of most proposed structures in various applications, 2D metamaterialsĬalled metasurfaces attracted more attention in recent years. Negative index, absorber, , wave manipulation, and invisibility cloaks. Keywords: Bessel beam, Chemical potential optimization, Graphene, Illusion, Metasurface, VortexĪUTHOR SUBMITTED MANUSCRIPT - JPhysD-121671.R1Ī metamaterial is an artificially engineered material made to obtain unusual properties such as a Modern information systems, data encryption, and THz communication applications. Phase, amplitude, and polarization control in various beamforming applications at THz spectrum for Indeed it has an exceptional capability for Limited to a specific structure for phase-only metasurface. Chemical potential optimization method in graphene-based coding metasurface is not Results show that the suggested method offers a feasible strategy for multifunctional metasurfaceĪpplications. Vortex beam, non-diffractive Bessel beam, and EM bump illusion. Metasurface to manipulate electromagnetic (EM) wave in the half-space and generate converged To investigate our proposed structure, we present a multifunctional reconfigurable Phase profile across the metasurface, the proposed device can manipulate the reflected waveĭynamically. Each meta-atom can change the reflection phase by choosing appropriateĬhemical potential that obtained by utilizing optimization-based methods. The proposed unit cell is composed of four distinct graphene patches in the same layer, which has a (GTP), which can control the reflection phase in a real-time manner at terahertz (THz) frequencies. This method suggests a straightforward approach by utilizing graphene tunable pixels
