In this study, the cylindrical wave diffraction by double strips with different lengths and boundary conditions are investigated. The scattered fields are found by the Numerical-Analytical Approach. The double-strip structure satisfies integral boundary conditions which are the generalization of Dirichlet and Neumann boundary conditions. The electric field, current distribution, and Total Radar Cross Sections are investigated. The results are compared with other methods and previous findings such as the Method of Moments and Physical Optics. The theoretical and numerical analyses indicate that the fractional order, the position of the line source have tremendous effects on the total-field distributions.

带有不同分数边界条件的双条的线源衍射

在这项研究中，研究了具有不同长度和边界条件的双条带的圆柱波衍射。散射场是通过数值分析方法找到的。双条纹结构满足积分边界条件，这是Dirichlet和Neumann边界条件的推广。研究了电场，电流分布和总雷达横截面。将该结果与其他方法和以前的发现（例如，矩量法和物理光学方法）进行了比较。理论和数值分析表明，分数阶，线源的位置对总场分布有很大的影响。
