Özet

The scattering of the H-polarized plane wave by a two-dimensional (2-D) parabolic reflector made of graphene placed in the free space is simulated by using the Method of Analytical Regularization (MAR) technique. The total scattering cross-section and absorption cross-section are computed, together with the field magnitude in the geometrical focus of reflector. The surface plasmon resonances are observed. Besides, the focusing ability of the reflector is studied in dependence of the chemical potential of the graphene.
