Wetting diagram for paranematic wetting when t = 0.1500 is approached from below, in the parameter space of the surface potential: quadratic coupling strength S s versus the modulus of the quartic coupling strength − η for h = 0.016, γ = 0.05, and D = 10 of the system: (a) without the quartic coupling and (b) with the quartic coupling.
