ABSTRACT

In this paper the rigorous solution of transverse electric (TE) and transverse magnetic (TM) plane wave scattering from a Perfect Electromagnetic Conductor (PEMC) strip located at the planar interface of two half spaces (dielectric and chiral medium) is presented by applying Kobayashi Potential (KP) method. Initially, the reflected field in dielectric and also transmitted Beltrami fields in chiral medium are divided into left and right handed fields. Then, contribution of the strip in terms of Bessel eigenfunctions is added as a perturbation to the dielectric and the chiral medium fields. Then, by applying the boundary conditions, utilizing the Weber–Schafheitlin (WS) discontinuous integrals and the Jacobi's polynomials, governing equations of infinite summations with unknown coefficients are derived. The infinite summations are effectively truncated with high numerical accuracy. Next, by solving the matrix equations, the unknown coefficients are calculated. Besides validating the method with the convergence analysis, an asymptotically comparative analysis with other investigations is also provided. Finally, the study of Echo Width (EW) for interesting parameters are depicted. The method is extremely accurate and is applicable to both narrow and wide strips. Also the presented formulations are validated by some methods (KP, physical optic and method of moment).

摘要

本文通过应用Kobayashi提出了位于两个半空间（介电和手性介质）平面界面处的完美电磁导体（PEMC）条的横向电（TE）和横向磁（TM）平面波散射的严格解决方案电位（KP）方法。最初，电介质中的反射场和手性介质中的传输Beltrami场被分为左手场和右手场。然后，将带的关于贝塞尔本征函数的贡献作为扰动添加到介电场和手性介质场。然后，通过应用边界条件，利用Weber-Schafheitlin（WS）间断积分和Jacobi多项式，导出具有未知系数的无限求和的控制方程。无限求和可以有效地以高数值精度截断。接下来，通过求解矩阵方程，计算未知系数。除了通过收敛性分析验证该方法外，还提供了与其他研究的渐近比较分析。最后，描述了回声宽度（EW）对有趣参数的研究。该方法非常精确，适用于窄条和宽条。提出的配方也通过某些方法（KP，物理光学和矩量法）进行了验证。描述了回声宽度（EW）对有趣参数的研究。该方法非常精确，适用于窄条和宽条。提出的配方也通过某些方法（KP，物理光学和矩量法）进行了验证。描述了回声宽度（EW）对有趣参数的研究。该方法非常精确，适用于窄条和宽条。提出的配方也通过某些方法（KP，物理光学和矩量法）进行了验证。
