Simulation results for $\lambda$ = 633 nm, n₀ = 1.52, n₁ = 1.39 with thickness d₁ and n₂ = 0.18344 + 3.4332i with thickness d₂ and n₃ = 1.34. (a) |r_p|² when d₂ = 30 nm and (b) |r_p|² when d₂ = 20 nm (c) Phase(r_p) in rad when d₂ = 30 nm and (d) Phase(r_p) in rad when d₂ = 20 nm. The colored curves shown in (a,b) are the interferometric mode positions calculated using Equation (3) and the LRSPP mode
