| Abstract: | Usually, a two-dimensional scattering problem for radar or other appli-cations means a cylindrical scatterer illuminated by a plane wave. But it is not suit-able for analysing the scattered fields in the case of EM exploration, in which the un-derground scatterer is illuminated by a three-dimensional emitter,or simply, apointsource. The latter has not yet been solved completely due to the infinitely extensionof the scatterer. In this papor, a hybrid method combining the GMT expanding incross-section and SDT for axial dimension is proposed, the numerical procedures areobviously simplified, especially for a larse crase-section. Various typical exaniplesincluding perfectly conducting and lossy dielectric cylinders with several differentcross-sections are given. |
