Abstract :
The authors compare the results obtained by the physical theory of diffraction (PTD) and the method of moments (MoM) in the frequency regime where their regions of applicability overlap with a view to identifying the deficiencies of the PTD. They then propose a hybrid technique for improving the PTD results, over a wide frequency range, by using a combination of the MoM solution and an extrapolation technique.<>
