  • The function of stability factor was discussed in FDTD calculation. Modification formula of two-order Mur condition including stability factor was derived. Taking example for line source, effects of stability factor on absorbing boundary capability and numerical stability were studied. Plane wave was added to three-dimensional calculation space as soft excitation source. The variety of RCS and convergence performance with stability factor was computed. Results show that increasing temporal increment is favorable when satisfying numerical stability condition.
