| Abstract: | The computational error characteristic of the complex ray expansion method (CREM), while it is applied to evaluating the scattering of cylinder surface with an incident plane wave, is discussed in this paper. A novel collective definition on the parameters of the CREM is proposed in order to simplify the modeling of computational error. It is verified the accuracy of numerical results can be improved greatly by appropriate selection of the parameters. |
| Keywords: | complex ray expansion incident plane wave electromagntic scattering accuracy |
