Abstract :
We examine the effect of the cell type on the accuracy of Yee-like schemes. The approach is built over an error bound introduced for the discrete counterparts of the constitutive laws. We specify which geometric properties of the cells have an effect on the approximation errors. The convergence properties of different cell types are demonstrated with numerical examples.
