We consider filamentary and planar large scale structures as possible refraction channels for electromagnetic radiation coming from cosmological structures. Using this hypothesis, it is possible to explain the quasar luminosity distribution and, in particular, the presence of "twin"and "brother" objects. The methods and details of the simulation are given.

Key words: cosmology: large scale structures, gravitational lensing -- waves -- methods: N-body simulation
