phenomenon was attributed to the effects of the junctions between the rods.

However, no detailed study on the relationship between anisotropy in electrical conductivity and the optical transparency of a two-dimensional film of partially oriented conducting rods has previously been performed. In this work, we consider continuous models of 2D systems where the rods have zero-width (i.e. an infinite aspect ratio) and they may intersect each other. For calculation of the filling fraction and electrical conductivity a discretization algorithm based on the use of a supporting mesh, viz., a square lattice of size $m\times m$ ($m = 64-2048$) was applied. The discretization of the structure of the infinitely thin rods is equivalent to the substitution of rods with polyominoes (e.g., see [@Golomb1994]). The cells of supporting lattice covered by rods were assumed to be nontransparent and electrically conducting. The Frank–Lobb algorithm was applied to evaluate the electrical conductivity.

The rest of the paper is constructed as follows. In Section \[sec:methods\], the technical details of the simulations are described, all necessary quantities are defined, and some test results are shown. Section \[sec:results\] presents our principal findings. Section \[sec:conclusion\] summarizes the main results.
