Transmission probability through a parallel delta-function-shaped magnetic double barrier as a function of the incident angle φ and γ with incident energy E _F  = 24 meV and distance L = 9d = 234 nm for potential barrier V ₃ = 40 meV. (b) The same as panel (a) but for potential barrier V ₂ = V ₄ = V = 40 meV. (c) Transmission probability as a function of the potential barrier V ₃ for a different incident angle with incident energy E _F  = 24 meV and distance L = 9d = 234 nm. The black solid line, red dashed line, green dotted, and blue dot-dashed line correspond to φ = 0 and γ = 0, φ = 0 and γ = π/12, φ = −π/6 and γ = 0, φ = −π/6 and γ = π/12, respectively. (d) The same as panel (c) but for the potential barrier V ₂ = V ₄ = V.
