E-case: Wave scattering and absorption by parabolic graphene reflectors versus the frequency in the THz range, for small-size reflector, d = 200 μm (a) and medium-size reflector, d = 1000 μm (b) Solid lines (black) and dashed lines (blue): ACS and TSCS for μ c =1 eV. Dash-dotted lines (red): TSCS for the PEC reflector. The other parameters are f/d = 0.3, T = 300 K, τ = 1 ps
