    Scattering and absorption performance of a microsize graphene-based parabolic reflector in the THz range illuminated by a complex line source
    (IEEE, 2017) Oğuzer, T.; Altıntaş, Ayhan
    The scattering and absorption characteristics of a two- dimensional (2-D) parabolic reflector made of graphene and placed in the free space is simulated using the Method of Analytical Regularization (MAR) technique. Reflector is illuminated by a complex magnetic line source having a directive beam-like antenna pattern and placed in the geometrical focus of reflector. The total absorbed power and forward and backward directivities are computed. The surface plasmon (SP) resonances are observed. Besides, the scattering performance of the reflector is studied in dependence of the chemical potential of the graphene.
