The magnetic field, 20 log|H /1 [A/m] | (normalized to its maximum value) (upper row) and the magnitude of the power flow density S (normalized to its maximum value) for a super-resonant, holey Ag-based CNR with h = 5D_CNR and different cut-out angles. The results are shown in the xy-plane (z = 0) as a function of the observation angle φ for (a), (d) ρ = 40 nm, (b), (e) ρ = 80 nm, and (c), (f) ρ = 120 nm.
