Task of falling wave on technology of TF / SF at the finite - difference solution of the d'Alembert and Maxwell's equations

The technique of searching of the collateral finite - difference solution of a wave equation and set of equations of Maxwell is offered, allowing to combine advantage and to avoid shortcomings of both made mention numerical methods of nanophotonics. In a two - dimensional case on test examples convergence of such decision, possibility a task of an incident wave on the TF/SF technology are shown.
