Reflection of the pulse from the lattice end.t= 75. Computation according to Eq. (35). Solid line is the reflected pulse, dotted line represents the tail of the incident pulse. Att= 75 the pulse leading edge, moving withv= 2, passed ≈ 150, lattice sites: 100 sites before reflection and 50 sites after reflection, MSRE < 10−4(numeric data are not shown),E= 1,C2= 0.5,N= 100.
