Same exact-rectangular-barrier formula as the 2D original's controls drive: T = 1/(1 + V₀²sinh²(κL)/[4E(V₀−E)]) when E<V₀ (tunneling), or T = 1/(1 + V₀²sin²(k₂L)/[4E(E−V₀)]) when E>V₀ (over-barrier). The ribbon shows the real probability-density envelope; particles sample pass/fail from the same T.
