    • Ray expansion in inhomogeneous and stochastic media 

      Chigarev, A. V.; Chigarev, Ju. V. (БНТУ, 2018)
      Simulation of wave propagation processes in inhomogeneous media is based on kinematic and dynamic principles for the process of ray propagation and wave surfaces (fronts) in different media. Huygens' principle of constructing wave fronts in according to algorithm of a contact transformation is easily implemented if the perturbation region is non-concave.
