- Abstract
In the present study, a new methodology for solving an eigenvalue problem and the two-dimensional E-polarized electromagnetic wave diffraction by the arbitrary shaped perfect electric conducting (PEC) scatterers is proposed. The approach is based on the Gaussian basis function and the Regularized Hankel's function. The study provides the theoretical background of the newly proposed approach in detail. By expanding the current density on the surface with the summation of Gaussian functions and approximating the Hankel function with regularization leads to having a simpler, compact, and novel approach to investigate the behavior of the electromagnetic field in the vicinity of the obstacles. Also, the numerical results including the comparison with the other methods are provided. The outcomes reveal that the proposed method can be employed for such a class of diffraction problems to solve the problem, numerically.
