Abstract :
The proposed approach combines the accuracy of the conventional rigorous methods with the flexibility of the high-frequency ray-tracing based techniques to handle complex real-world problems. We have obtained excellent results for a wide variety of test cases and we believe that the method is especially well suited for the analysis of large antennas, arrays and scattering problems for which rigorous methods cannot be applied.
