Transformation of Field in Regular Waveguide via Phase Correctors

The problem of the electromagnetic field transformation in regular waveguides is solved with use of phase correctors placed at its input and output. The variational statement of the problem consists in maximization of inner product of the prescribed and received fields. The solution is carried out by an iterative procedure improves the functional value in each step. The approach permits generalization to the case of more than two correctors. Results of numerical calculations are presented.
