Numerical solutions of equations (7) and (11) shown by red solid curves; model for small smectic cone angle θ and chevron tilt angle δ (blue dashed curves): (a) the dependence of the layer tilt δ upon the normalized x-coordinate; (b) the spatial dependence of the azimuthal angle within the monolayer sample of chevron SmC*. Parameters of the problem are E = 10⁴V · m⁻¹, K_u = 5 × 10⁻¹² N, B = 4 × 10⁶ N, and μ = 0.85.
