Numerical artifacts caused by 1D and 2D mesh refinements in the FDTD method are investigated. The effect of numerical reflections previously known from simulation practice is mathematically confirmed. It is shown that the magnitude of reflections can be accurately predicted by combining the numerical dispersion relations in the two mesh subregions with the electric field continuity condition at the interface. To this end, numerical emulation of Snell's law and non-orthogonality of the numerical field and propagation vectors are addressed. The theory is validated for the 2D TE modes at normal and oblique incidence.
