| Abstract: | An FV-FD hybrid method is proposed by presenting a novel connecting condition between the two algorithms which match in time in different schemes. The RCS of a 2-D PEC cylinder illuminated by the TE wave is calculated as a numerical example, which shows that the method has the advantages of higher accuratly, reduction in running time and saving of computational space . |
