A rigorous analytical method for transient dynamics description in a
cylindrical lens is developed and used to describe a possibility of beam controlled
deflection via material tuning. The complex source point concept is used to simulate
beam passing through the lens. Details of both the transient response and steady-state
regime are described. The excited fields are described using a rigorous mathematical
approach based on analytical solution in the Laplace transform domain and accurate
evaluation of residues at singular points of the obtained functions.
