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.EnglishElectromagnetic scatteringGraphene reflectorAcoustic wavesDifferential equationsDirective antennasGrapheneMagnetic line sourceMethod of analytical regularizationParabolic reflectorScattering and absorptionScattering and absorption characteristicsParabolic antennasScattering and absorption performance of a microsize graphene-based parabolic reflector in the THz range illuminated by a complex line sourceConference Paper10.1109/DIPED.2017.81006192165-3593
