Recognition of Irregular Waveguide Geometry Using Opposite Directions Technique

An inverse problem of irregular waveguide shape recognizing with usage of the moving point source inside it, is considered. A combined algorithm is proposed for solving the appropriate direct problem, based on the known cross-section method with applying the opposite directions technique. In combination with the local variations method, this technique most fully uses the information about fixed parts of the recognized waveguide. This approach allows us to minimize the computation costs in each step of the iteration procedure
