We demonstrate a new implementation of bidirectional eigenmode propagation algorithm for modeling of three-dimensional waveguide structures. The algorithm is based upon expansion of unknown field into set of orthogonal eigenmodes which are searched using a full vector finite-difference modesolver. Numerical examples demonstrate convergence behaviour and typical circumstances in which the technique may be useful.
