Abstract

The study presents electromagnetic scattering by arbitrarily located double strips with perfect electric and/or magnetic conducting surfaces. The study generalizes not only the physical dimension, location, and orientation of the strips but also, the boundary conditions on each strip are generalized and variable. It can be Dirichlet or Neumann boundary conditions. Since the study considers numerous parameters as the variable, the comparison between the present study and the literature is investigated in detail. Geometries such as parallelly located double strips with fractional boundary conditions, impedance double strips, and wedge problems are considered to compare. Besides, the proposed methodology is compared by the method of moments, the method of auxiliary sources, and the orthogonal polynomials approach. The suggested research investigates the electromagnetic scattering by finite wedge and arbitrarily located two strips with different boundary conditions and widths for the first time since each strip can have different widths and boundary conditions (Dirichlet or Neumann). The results reveal that the angle between the strips, the rotation of the strips, width of the strip have noticeable effects on the scattered field and total radar cross-sections. Between the strips, resonances are observed and their characteristics have a substantial dependency on the boundary conditions.

任意位置的导电和/或导磁双层带的电磁散射
该研究介绍了具有完美电导和/或磁导表面的任意位置双条带的电磁散射。该研究不仅对条带的物理尺寸、位置和方向进行了概括,而且对每个条带上的边界条件进行了概括和变量化。它可以是 Dirichlet 或 Neumann 边界条件。由于本研究将众多参数作为变量,因此将详细研究本研究与文献之间的比较。比较中考虑了具有分数边界条件的平行双条带、阻抗双条带和楔形问题等几何形状。此外,还用矩量法、辅助源法和正交多项式法对建议的方法进行了比较。由于每个条带都可以有不同的宽度和边界条件(Dirichlet 或 Neumann),建议的研究首次考察了有限楔形和任意定位的两个具有不同边界条件和宽度的条带的电磁散射。结果表明,条带之间的角度、条带的旋转、条带的宽度对散射场和雷达总截面有明显的影响。在条带之间可以观察到共振,其特征与边界条件有很大关系。
