论文摘要
我们提出了一种数值方法，用于从一部分用石墨烯部分覆盖的介电缸的电磁散射溶液。它基于圆柱体内外的磁场的经典傅立叶孔扩展，我们在存在石墨烯的存在下应用了临时边界条件。由于石墨烯片边缘的电场的奇异性，我们引入了辅助边界条件。结果是特别简单且非常有效的方法，允许研究此类结构的衍射。我们还强调了我们归因于涂层缸的表面模式的多种等离子共振的存在。
We present a numerical approach for the solution of electromagnetic scattering from a dielectric cylinder partially covered with graphene. It is based on a classical Fourier-Bessel expansion of the fields inside and outside the cylinder to which we apply ad-hoc boundary conditions in presence of graphene. Due to the singular nature of the electric field at the edges of the graphene sheet, we introduce auxiliary boundary conditions. The result is particularly simple and very efficient method allowing the study of diffraction from such structures. We also highlight the presence of multiple plasmonic resonances that we ascribe to the surface modes of the coated cylinder.
