This paper is concerned with a numerical investigation of magnetic wave, scattered by a conducting cylinder to check the accuracy of numerical results based on the discrete ray tracing method (DRTM). First, the boundary profile of the cylinder is approximated in terms of piecewise-linear plates. Source and image rays are searched for the approximated boundary composed of finite number of plates. Second, numerical computations are carried out for total fields, superposing the scattered fields from each conducting plate, using source and image diffraction coefficients with the Fresnel function. Numerical results of H-wave based on DRTM are compared with rigorous solutions given by use of the Bessel and Hankel functions. Finally, it is demonstrated that the DRTM results of H-wave, are in good agreement with those results obtained by the rigorous solutions and we show an appropriate guideline to discretize the boundary to achieve as small errors as possible. |
