We numerically analysed various localized modes formed by light beam propagation through one-dimensional composite lattices consisting of two structurally different linear lattices and a linear defect (LD) in one of them. The localized modes are found in the area between the interface and the LD, near the interface and around the LD. It has been confirmed that a LD narrower than the other waveguides (WGs) in the array is better potential barrier and captures the light better than a LD that is wider than the other WGs in the array. Also, it has been shown that a LD narrower than the other WGs in the lattice captures the light more efficiently than any saturable nonlinear defect (ND) of the same width as other elements of the lattice. On the other hand, it is obtained that the influence of a LD wider than the other WGs in the array on light propagation can be mimicked by insertion of an adequate ND whose width coincides with that of the other WGs. Depending on the defect size, its positi...on and input beam parameters, controllable beam trapping, reflection and refraction are observed.
