Abstract
The nonstandard (NS) finite difference time domain (FDTD) algorithm delivers high accuracy on a coarse numerical grid, but in many problems the dominant source of error is the representation of objects on the grid. The error due to the representation is especially large near resonances. In this paper we address some methods to reduce representation error based on Mie theory on the theory of layers.
