CONSERVATIVE DIFFERENCE SCHEME FOR THE PROBLEM OF FEMTOSECOND PULSE PROPAGATION IN LAYERED ABSORBING MEDIUM WITH NONREFLECTING BOUNDARY CONDITIONS

摘要

Several kinds of nonreflecting boundary conditions are proposed in this work for the problem of femtosecond pulse propagation in periodically absorbing medium on the basis of computer simulation. The constructed conditions are compared. The possibility of decrease of the amplitude of a reflected wave is shown up to less than 0.1% as compared to the amplitude of an incident wave.
