N2 - The antenna transfer function in multiple knife-edge diffraction scenarios is characterized with the bidirectional ray-tracing method. The receiving and the transmitting antennas are located near or at the optical boundaries where the traditional Uniform Theory of Diffraction (UTD) solution fails in terms of accuracy. The new algorithm overcomes the accuracy issues of UTD where both transmitter and receiver antennas are utilized for ray launching. The rays are captured on a large interaction surface and the transfer function is computed by evaluating the reciprocity integral over this surface. The simulation results are compared to the Vogler method, which is used as reference, and the merits of the bidirectional ray-tracing in terms of accuracy are demonstrated.
