(color online) The appropriate parameters are: w 1 ( x ) = x , w 2 ( x ) = 0.1 sin ( x ) , ε = 1, k1 = 1, k2 = 0.75, c1 = 2, c2 = 1, and θi = 1 (i = 1,2). (a) The real part of the corresponding potential function. (b) The imaginary component of the corresponding potential function. (c) Periodic wave structure of u(z,x).
