dc.description.abstractUnconditionally stable multi (4, 6, and 8) split-step finite-difference time-domain methods are isotropic for a certain space step size and a stability factor. It is shown in this letter that for small step sizes the phase velocity errors can be corrected by using a factor which is a function of the product of the space step size and the stability factor. This way, it is not necessary to obtain the multiplication factor each time when a different space step size is used. Also, by using this multiplication factor zero phase velocity error can be obtained in all directions at a chosen frequency. Performance analyses have shown that the method is also wideband.
