  • Combined plasmon-resonance and photonic-jet effect in the THz wave scattering by dielectric rod decorated with graphene strip
    Journal of Applied Physics, 2019
    Co-Authors: S.v. Dukhopelnykov, Ronan Sauleau, Maria Garcia-vigueras, Alexander I. Nosich

    Abstract:

    We consider the scattering of an H-polarized plane wave by an infinite dielectric rod with a conformal graphene strip of arbitrary Angular Width, placed at the rod rear side. Our analysis is based on the hypersingular integral equation for the current induced on the strip. Discretization of this equation is carried out by the Nystrom-type method, which has a guaranteed convergence. This meshless trusted computational instrument enables us to plot the dependences of the absorption cross section and the total scattering cross section on the strip Angular Width and the frequency, in a wide range from 1 GHz to 6 THz. We concentrate our analysis on studying the interplay between the broadband photonic-jet effect of the dielectric rod and the reasonably high-Q resonances on the plasmon modes of the graphene strip. It is found that as the photonic jet becomes brighter with higher frequencies, the plasmon-mode resonances become more intensive as well.We consider the scattering of an H-polarized plane wave by an infinite dielectric rod with a conformal graphene strip of arbitrary Angular Width, placed at the rod rear side.

  • Scattering and Absorption of the H-polarized Plane Wave of THz Range by a Circularly Curved Graphene Strip in the Free Space
    , 2019
    Co-Authors: S.v. Dukhopelnykov, M.g. Vigueras, Ronan Sauleau

    Abstract:

    We consider the scattering of an H-polarized plane wave by an infinite circularly curved graphene strip of arbitrary Angular Width, placed in the free space. Our analysis is based on the hypersingular integral equation for the current induced on the strip. Discretization of this equation is carried out by the Nystrom-type method that has a guaranteed convergence. This trusted computational instrument enables us to plot the dependences of the extinction cross-section (ECS) on the frequency, strip Angular Width and physical Width, and its radius of curvature. We derive approximate equation for the resonance frequencies of the graphene plasmon modes and demonstrate its agreement with full-wave computations in the THz range. © 2019 IEEE.
