a Line pattern formed with solution (10 mg C8-BTBT + 10 mg PS)/ml. b Square-grid pattern formed with solution 10 mg C8-BTBT/ml. c Zig-zag pattern formed with solution (10 mg C8-BTBT + 5 mg PS)/ml. d Fence-like pattern formed with solution (10 mg C8-BTBT + 10 mg PS)/ml. e Single harmonic wave with vector in the x-direction. f Two harmonic waves with vectors in two orthogonal directions. g Single harmonic wave of vector in the y-direction with a periodic phase swing. h Single harmonic wave of vector in the y-direction superimposes with a wave package of vector in the x-direction. For the simulated patterns only high concentration parts are displayed, as the precipitation starts around the peaks of the waves.
