| 摘 要： | 利用流基混合法与有限元法相结合计算开槽电大尺寸目标的表面行波散射，首先利用流基混合法算出无槽时的目标表面波散射，再根据等效原理在口径处与有限元法进行耦合得到开槽电大尺寸目标的总体表面波散射。数据结果证明此方法是准确和高效的。

| Abstract: | A hybrid technique to calculate the surface wave scattering of electrically large bodies with cracks by combining the current based hybrid method and the finite element method is presented. Based on the equivalent theorem, the field scattered by the body with cracks can be divided into two parts: the scattering from the body without cracks and that from the cracks. The first part is calculated by the current based hybrid method and the total scattering field of the body with cracks is obtained by using the hybrid technique. Some numerical results have been obtained, showing the feasibility of the proposed method. |
