    "abstract": "We outline specific features of numerical simulations of metamaterial wedges\nand interfaces. We study the effect of different positioning of a grid in the\nYee method, which is necessary to obtain consistent convergence in modeling of\ninterfaces with metamaterials characterized by negative dielectric permittivity\nand negative magnetic permeability. We demonstrate however that, in the\nframework of the continuous-medium approximation, wave scattering on the wedge\nmay result in a resonant excitation of surface waves with infinitely large\nspatial frequencies, leading to non-convergence of the simulation results that\ndepend on the discretization step.",
